AB  - The inhibitive effect of a seaweed (SM) alcoholic extract on MS corrosion immersed in 1 M HCl, for 30 min, was evaluated by the WL method and PPD technique. The protective film was investigated by the Vickers hardness test. WL revealed that 500 ppm SM offered 84 % IE against MS corrosion in 1 M HCl. The inhibitor molecules adsorption onto the metal surface obeyed Langmuir’s adsorption isotherm. The R2 value was very high (0.998). The PPD study showed that Ecorr slightly shifted to the anodic side. It was inferred that SM functions as a mixed type of corrosion inhibitor, since the shifts were relatively small. In SM presence, LPR value increased and Icorr decreased. Due to the blanket effect (formation of a protective film on the metallic surface, which was found to be a monolayer, blocking anodic and cathodic sites), the electrons transfer from the metal into the solution was blocked. Vickers hardness of the inhibited MS surface was lower than that of the polished one, but higher than that of the corroded one. The outcome of the study may be used in the pickling industry, where HCl is used to remove the rust from the metal surface, simultaneously not attacking it. © 2023, Sociedade Portuguesa de Electroquimica.

Journal of Coastal Research, 38(3), 567–577. Coconut Creek (Florida), ISSN 0749-0208. The Boğaçay is a river situated in the Konyaaltı district of Antalya. In 2017, Antalya Metropolitan Municipality implemented a large project in which the river bed was excavated to 1.5 m below sea level. The aquifer is vital for meeting the drinking water needs of the city of Antalya. The goal of this research is to discover the applications that may be made to combat seawater intrusion and nutrient contamination, both of which were brought to the forefront by the Boğaçay Project. In this work, modeling was used to estimate the extent to which agricultural best management practices (BMPs) will be efficient in reducing pollutant load. In BMP modeling with the soil and water assessment tool (SWAT), a decrease of 39%, 38%, and 38% is anticipated in the 5-day biochemical oxygen demand (BOD5), total phosphorus, and total Kjeldahl nitrogen loads, respectively. Sediment accumulated in the channel, and sediment transport occurred on the beach due to coastal erosion. Coastal erosion of up to 25 m was observed from the project's beginning to the present. Substantial land base pollution because of the diffused sources was found. Saltwater intrusion in the Boğaçay River estuary functions as a catalyst in the production of poor odor and appearance, as well as the rapid expansion of algae. The municipality is attempting to remedy this problem by periodic harvesting, which is an overly expensive and ineffective option. Instead, the elevation of the riverbed should be restored to preproject levels to prevent additional environmental and geographic damages.

AB  - Due to the importance of underwater exploration in the development and utilization of deep-sea resources, underwater autonomous operation is more and more important to avoid the dangerous high-pressure deep-sea environment. For underwater autonomous operation, the intelligent computer vision is the most important technology. In an underwater environment, weak illumination and low-quality image enhancement, as a pre-processing procedure, is necessary for underwater vision. In this paper, introduced the Deep learning based Underwater Metal object detection using input Image data by using several step to improve the model performance. In this experimentation we are using TURBID dataset 100 images to validate the performance. And also we compare the performance result by given the input images in different validation level. In first input image is initially preprocessed and that images is given to the KFCM-Segmentation. The segmented images are given to the DWT Extraction to extract the features from those images. And finally the Convolution Neural Network (CNN) is used to classify the images to detect the objects. Also this proposed model attained the classification accuracy of 98.83%. This method is much suitable for detect the objects in underwater robotically. Metallic parts of machines of ships or aero planes may submerge in sea water. They may undergo corrosion when they come in contact with sea water which contains 3.5% sodium chloride. This is most commonly responsible for the corrosive nature of the sea water. The robots made of materials such as mild steel may also undergo corrosion when they come in contact with sea water, while is search. If a paint coating is given, it will control the corrosion of these proposed materials. Hence this work is undertaken. Mild steel is coated with Asian guard red paint. Corrosion resistance of mild in3.5% sodium chloride solution is measured before coating and after coating by electrochemical studies such as such as polarization study and AC impedance spectra. The corrosion inhibition efficiency offered by red paint to mild steel in 3.5% sodium chloride is 99.98%.

AB  - Buried metal objects in sea water may undergo corrosion because of the corrosive ions such as chloride ions present in seawater. However a paint coating may control the corrosion of the metal objects such as robots. Corrosion resistance of mild steel in 3.5 % sodium chloride solution before and after coating with Asian guard red paint has been evaluated by polarization study and AC impedance spectra. In presence of Asian guard red paint, the linear polarization resistance increases, corrosion current decreases, charge transfer resistance increases, double layer capacitance decreases and impedance value increases. That is corrosion resistance of mild steel objects in 3.5 % sodium chloride solution increases after coating with Asian guard red paint.

AB  - The hull plates of the ship made of mild steel (MS) are always in contact with sea water are always in contact with aggressive ions such as chloride ions present in sea water.The corrosion resistance of the hull plates of the ship made of mild steel has been investigated by polarization study. Sandalwood oil extract containing 5 g each of Cardamom (disambiguation), Clove (disambiguation), Nutmeg, India Sambrani (loban), Chrysopogon zizanioides, commonly known as vetiver and Camphor was used as corrosion inhibitor along with Trisodium citrate (TSC), sodium dihydrogen phosphate (SDP) and Zn2+. The corrosion resistance was measured in the absence and presence of various inhibitor systems: Trisodium citrate (TSC) 100 ppm+ Zn2+ 50ppm system, sodium dihydrogen phosphate (SDP) 100 ppm+ Zn2+ 50ppm system, Oil coated (3days) MS, Oil coated (3days) MS +TSC 100 ppm+ Zn2+ 50 ppm system and Oil coated (3days) MS +SDP100 ppm+ Zn2+ 50 ppm system were used. It is observed that when mild steel is immersed in SW+TSC 100 ppm+ Zn2+ 50ppm system, the corrosion resistance of MS increases. When mild steel is immersed in SW+ SDP 100 ppm+ Zn2+ 50ppm system, the corrosion resistance of MS increases. When mild steel is immersed in Oil coated (3days) MS in Sea water system, the corrosion resistance of MS increases. When mild steel is immersed in Oil coated (3days) MS in SW+TSC 100 ppm+ Zn2+ 50ppm system, the corrosion resistance of MS increases. When mild steel is immersed in Oil coated (3 days) MS in SW+ SDP 100 ppm+ Zn2+ 50ppm system, the corrosion resistance of MS increases. This is revealed by the fact that there is increase in LPR value and decrease in corrosion current value. The corrosion potential is shifted to anodic side. This indicates that in this inhibitor system, the anodic reaction of metal dissolution is controlled predominantly. This implies that these inhibitor systems may be coated on mild steel surface used as hull plates to prevent corrosion of mild steel in sea water.

AB  - The inhibitive effect of an alcoholic extract of a seaweed, namely, Sargassum Muticum, in controlling corrosion of mild steel in 0.5 N HCl has been evaluated by weight loss method (immersion period 1 day) and electrochemical techniques such as polarization study and AC impedance spectra. The protective film has been investigated by AFM and Vickers Hardness test. Weight loss method reveals that 500 ppm of inhibitor offers 99% inhibition efficiency to mild steel immersed in 0.5 N HCl. The adsorption of inhibitor molecules on the metal surface follows Langmuir adsorption isotherm. The R2 value is very high, 0.998. Polarization study reveals that the corrosion potential is slightly shifted to anodic side. It is inferred that the inhibitor solution functions as mixed type corrosion inhibitor. In the presence of the inhibitor, the linear polarization resistance (LPR) increases and the corrosion current decreases. Because of the Blanket effect (formation of a protective film on the metal surface blocking the anodic sites and cathodic), electron transfer from the metal to the bulk of the solution is blocked. AC impedance spectra confirm the formation of a protective film on the metal surface. As the inhibitor concentration increases, the Rct value increases and the double layer capacitance (Cdl) decreases, the impedance increases and the phase angle increases due to the blocking effect on the metal surface. It is found to be a monolayer of protective film. The Vickers hardness of the inhibited metal surface is lower than that of polished metal but higher than that of corroded surface. The average roughness, RMS roughness and maximum peak-to-valley height of inhibited metal surface are lower than those of corroded metal surface but higher than those of polished metal surface. The outcome of the study may be used in pickling industry where HCl is used to remove rust and at the same time metal surface is protected.

AB  - In this paper, analyzed are the effects of the plasma spray distance on the microstructure and mechanical properties of the NiCrAlCoY2O3 coating layers deposited at atmospheric pressure. The microstructure and mechanical properties of the coating layers are under the influence of the interaction of plasma particles (ions and electrons) with powder particles, providing the transfer of velocity and temperature of the plasma particles onto the powder particles. The effect of the interaction is directly dependent on the time the powder particles were present in the plasma which is defined by distance of the plasma gun from the substrate, depending on the granulation of the powder, the melting point and specific gravity. In order to obtain homogeneous and denser coating layers with high adhesion, in the experiment three distances from the substrate were used: 95 mm, 105 mm and 115 mm. The layers were deposited on thin sheets of AlMg1 aluminum thickness of 0.6 mm. Evaluation of mechanical properties of the layers was carried out by examining microhardness using the HV0.1 method and the bond strength by tensile testing. The morphology of the powder particles was examined on the SEM, while the microstructure of the layers was evaluated under a light microscope in accordance with the Pratt Whitney standard. The results of the experiment showed that the distance from the substrate substantially influenced the structure and mechanical properties of the coating layers. The best deposited layers were examined in the system with the ZrO224%MgO ceramic coating, which have proved to be reliable protectionfrom high temperature and abrasive rocket jet fuel.

AB  - The aim of this study was to deposit multi-functional ZrO28%Y2O3 coating layers using the plasma spray technology and then to characterise such layers. In combination with other biomedical ceramics, this coating is intended for the application in implant surface modification. The examination was focused on the mechanical properties and microstructure layers. Using the atmospheric plasma spraying, duplex ZrO28%Y2O3/Ni22Cr10Al1Y coating system was deposited on the X15Cr13 stainless steel, with two different thicknesses of the bond and ceramic coatings. The microstructure was analysed using an optical microscope, including the assessment of the content of micropores. The morphology of powder particles and ceramic coating surfaces were examined on a scanning electron microscope (SEM). The quality of the ZrO28%Y2O3 layers makes them suitable for the application and combination with other materials to create a system of biomedical or multifunctional coatings.

AB  - The aim of the study was a preliminary examination on water quality (U01-U08) in Rasina area, through the standard physico-chemical parameters: temperature, pH, conductivity, turbidity and total organic matter. All samples were odorless and tasteless. The results for temperature, pH and conductivity were within the values defined by Regulation on the quality of drinking water, except for the pH value of the sample U05. Increased turbidity was observed in the sample U03 (13.5 NTU). On the basis of the results for total organic matter (1.2 to 5.5 mg O2/L) that were within the permissible range, it can be concluded that all the studied samples belong to the first (I) class water quality.
AB  - Cilj rada bio je preliminarno ispitivanje kvaliteta voda sa područja Rasinskog okruga (U01-U08) određivanjem standardnih fizičko-hemijskih parametara: temperature, pH-vrednosti, provodljivost, mutnoće i ukupne organske materije. Svi uzorci su bili bez mirisa i ukusa. Dobijeni rezultati za temperaturu, pH i provodljivost bili su u okviru vrednosti predviđenih Pravilnikom o kvalitetu vode za piće, osim pH vrednost uzorka U05. Povišena mutnoća zabeležena je u uzorku U03 (13,5 NTU). Na osnovu vrednosti za ukupne organske materije (1,2-5,5 mg O2/L) koje su bile u granicama dozvoljenih može se zaključiti da svi ispitivani uzorci pripadaju vodama prve (I) klase kvaliteta.

abstract = "The aim of the study was a preliminary examination on water quality (U01-U08) in Rasina area, through the standard physico-chemical parameters: temperature, pH, conductivity, turbidity and total organic matter. All samples were odorless and tasteless. The results for temperature, pH and conductivity were within the values defined by Regulation on the quality of drinking water, except for the pH value of the sample U05. Increased turbidity was observed in the sample U03 (13.5 NTU). On the basis of the results for total organic matter (1.2 to 5.5 mg O2/L) that were within the permissible range, it can be concluded that all the studied samples belong to the first (I) class water quality., Cilj rada bio je preliminarno ispitivanje kvaliteta voda sa područja Rasinskog okruga (U01-U08) određivanjem standardnih fizičko-hemijskih parametara: temperature, pH-vrednosti, provodljivost, mutnoće i ukupne organske materije. Svi uzorci su bili bez mirisa i ukusa. Dobijeni rezultati za temperaturu, pH i provodljivost bili su u okviru vrednosti predviđenih Pravilnikom o kvalitetu vode za piće, osim pH vrednost uzorka U05. Povišena mutnoća zabeležena je u uzorku U03 (13,5 NTU). Na osnovu vrednosti za ukupne organske materije (1,2-5,5 mg O2/L) koje su bile u granicama dozvoljenih može se zaključiti da svi ispitivani uzorci pripadaju vodama prve (I) klase kvaliteta.",

AB  - Solutions of milk protein concentrate, whey protein concentrate and bovine serum albumin (BSA) were treated with polyacrylic hydrogel to establish whether the hydrogel could be used for decontamination of heavy metal ions from milk protein-based products. The obtained results indicated that swelling of hydrogel in these solutions had different effects on their mineral, trace element and total protein content. Total protein and phosphorus content increased in milk protein concentrate and whey protein concentrate solutions after swelling of hydrogel without changes in their protein compositions. On the other hand, the protein content in BSA solution decreased after swelling. The content of Na did not change in milk protein concentrate solution, whereas it significantly increased in whey protein concentrate solution after hydrogel swelling. The content of Ca and Mg was reduced after the swelling in milk protein concentrate and whey protein concentrate solutions for 20.3-63.4 %, depending on the analysed sample and the mineral. The content of Zn did not change during swelling, whereas the content of Fe, Cu, Mn, Ni and Pb significantly decreased after hydrogel swelling in all analysed samples. According to the obtained results, the addition of polyacrylic hydrogel to milk and whey protein concentrate solutions can significantly decrease the content of heavy metal ions without affecting their protein composition. Therefore, this work could be useful in developing a new technological process for heavy metal purification of milk protein-based products.

AB  - Conventional treatment technologies for the removal pollutants from the environment usually aren’t economically viable or may further generate huge quantity of toxic chemical sludge which requires further treatment. Biosorption is emerging as a potential alternative technique to the existing conventional technologies; its application is economically acceptable because it reuse biological materials with their major advantages: low cost, high efficiency, renewability, minimization of chemical or biological sludge, easy regeneration of biosorbents and possibility of metal recovery.

AB  - Plants have an important role in circuit of heavy metals in nature. Heavy metals are input into food chains mainly through plants. One of the ways in which heavy metals are input into food products is through contaminated plants and animals used for their production. So, if the plants are cultivated on soil with high content of heavy metals then one part of these metals will be input into their organism. The usage of such plants for domestic animals nourishment will lead to their contamination with heavy metals. Meat, milk and eggs of these animals will be of poor quality considering the high level of heavy metals in them. The other, not less significant way of contamination of food products with heavy metals is the technological process in which they have been made. Namely, due to some irregularities in technological processes it can come to input of certain metals in amounts which are higher than regulated. It can come to contamination by metal particles during its mincing in the mill, by irregular keeping and storage, and as one of the main sources of contamination is the air in the industrial zones. Plants assimilate undesired metals from the soil, and in certain conditions through leaves. These elements are accumulated largely in the root area than in organs above earth. That is the reason why the knowledge of mechanisms of accumulation, distribution and metabolism of heavy metals in plants is of high ecological, scientific and practical significance.

abstract = "Plants have an important role in circuit of heavy metals in nature. Heavy metals are input into food chains mainly through plants. One of the ways in which heavy metals are input into food products is through contaminated plants and animals used for their production. So, if the plants are cultivated on soil with high content of heavy metals then one part of these metals will be input into their organism. The usage of such plants for domestic animals nourishment will lead to their contamination with heavy metals. Meat, milk and eggs of these animals will be of poor quality considering the high level of heavy metals in them. The other, not less significant way of contamination of food products with heavy metals is the technological process in which they have been made. Namely, due to some irregularities in technological processes it can come to input of certain metals in amounts which are higher than regulated. It can come to contamination by metal particles during its mincing in the mill, by irregular keeping and storage, and as one of the main sources of contamination is the air in the industrial zones. Plants assimilate undesired metals from the soil, and in certain conditions through leaves. These elements are accumulated largely in the root area than in organs above earth. That is the reason why the knowledge of mechanisms of accumulation, distribution and metabolism of heavy metals in plants is of high ecological, scientific and practical significance. Especially because heavy metals are among toxic matters which pollute the environment. This is the reason why wheat is selected for the analysis of the influence of heavy metals on plant culture in this paper. Wheat has dominant role in world’s diet, characteristic of strategic product and it covers significant part (almost one third) of total agricultural area of plants culture planted.",

AB  - In this paper, studied was the melting of W powder particles in plasma, their behavior at oxidation as well as the mechanism of hardening on the surface of the substrate. Tungsten coating layers were deposited with vacuum plasma spray technology (VPS) on the test specimens of steel Č.4171 (X15Cr13 EN10027). VPS technology has advantages over the APS technology due to decreased oxidation of melted powder particles, by producing a coating with a controlled proportion of micro pores and greater uniformity of the deposited layers. Evaluation of mechanical characteristics of the layers was done by examining the microhardness using the HV0.3 method and tensile bond strength by tensile testing. The microstructures of the deposited layers were analyzed by means of optical microscopy (OM) and scanning electron microscopy (SEM). The results obtained showed that the tungsten coating consisted of well melted particles that interconnected and were overlapping, which shows a typical lamellar microstructure. Present in the microstructure are micro pores in very small proportion at the inter-lamellar boundaries. Tests have shown that layers of W coating deposited by plasma spray in inert gas shielding at low pressure have good mechanical properties and microstructure, which in the fully enables its use in exploitation.

AB  - Primordial radionuclides present in the rocks and minerals of the earth's crust are naturally occurring source of radiation that has important impact on human health. Therefore, it is essential to evaluate origin, mobility and transfer of natural radionuclides in ecosystem. Our paper represents the results of influence of mineral composition, sand-, silt-, and clay-size mechanical fraction and heavy mineral fraction on distribution and mobility of natural radionuclides 238U, 232Th, 226Ra and 40K in profiles of soil type rigosol, from the area of school estate good "Radmilovac" of Faculty of Agriculture, Zemun, University of Belgrade. Methods used were X-ray powder diffraction, heavy liquid mineral separation, HCBr3, scanning electron microscopy (SEM) and gamma-ray spectrometry. Analysis of the results showed correlation of natural radionuclides with heavy mineral fraction (Fe oxides and hydroxides, epidote, ilmeniterutile, staurolite and zircon, garnet, amphibole) and secondary minerals (Ca montmorillonite, mix layer silicates (MSS), illite, kaolinite and vermiculite).

AB  - The DSC method has been employed to monitor the kinetics of reticulation of aqueous polyurethane systems without catalysts, and with the commercial catalyst of zirconium (CAT®XC-6212) and the highly selective manganese catalyst, the complex Mn (III)-diacetylacetonemaleinate (MAM). Among the polyol components, the acrylic emulsions were used for reticulation in this research, and as suitable reticulation agents the water emulsible aliphatic polyisocyanates based on hexamethylendoisocyanate with the different contents of NCO-groups were employed. On the basis of DSC analysis, applying the methods of Kissinger, Freeman-Carroll and Crane-Ellerstein the pseudo kinetic parameters of the reticulation reaction of aqueous systems were determined. The temperature range of the examination was from 500C to 4500C with the heat rate of 0.50C/min. The reduction of the activation energy and the increase of the standard deviation indicate the catalytic action of the selective catalysts of zirconium and manganese. The impact of the catalysts on the reduction of the activation energy is the strongest when using the catalysts of manganese and applying all the three afore-said methods. The least aberrations among the stated methods in defining the kinetic parameters were obtained by using the manganese catalyst.

U ovom radu za umrežavanje od poliolnih komponenti korišćene su akrilne emulzije a kao pogodni umreživači koričćeni su vodoemulgujući alifatični poliizocijanati na bazi heksametilendiizocijanata sa različitim sadržajem NCO-grupa. Na osnovu DSC-analize, metodama Kissinger-a, Freeman-Carrollaa i Crane-Ellerstein-a, određeni su prividni kinetički parametri reakcije umrežavanja vodenih sistema. Temperaturni opseg ispitivanja koričćen je od 50 do 450oC sa brzinom grejanja od 0.5oC/min. Smanjenje energije aktivacije i povećanje standardne devijacije ukazuju na katalitičko dejstvo selektivnih katalizatora cirkonijuma i mangana. Učešće katalizatora u smanjenju energije aktivacije je najveće kod katalizatora mangana, korišćenjem sve tri bbbmetode izračunavanja kod ispitivanih uzoraka u odnosu na cirkonijumov katalizator. Najmanja odsupanja između pomenutih metoda u određvanju kinetičkih parametara dobijena su korišćenjem manganovog katalizatora.

AB  - The unmodified GY epoxy resin (Vantico AG) was crosslinked by the aliphatic and cycloaliphatic EH polyamine adduct (Solutia-Vianova) in the different stoichiometric ratio. The optimal time of total crosslinking was determined by indirect measuring of the film hardness. The degree of the epoxy resin crosslinking and the quantity of unreacted epoxy groups have been monitored by the spectroscopic FT-IR method. The content and intensity changes of hydroxy group were correlated to the extent of epoxy reaction and crosslinking degree. By the parameters correlation and a period of resins application, optimal resin/hardeners stoichiometric ratio was defined. It was prerequisite for three-component epoxy system forming which is comparatively more elastic, adhesion and waterproof.

AB  - The use of fast FT-IR spectroscopy as a sensitive method to estimate a change of the crosslinking kinetics of epoxy resin with polyamine adducts is described in this study. A new epoxy formulation based on the use of polyamine adducts as the hardeners was analyzed. Crosslinking reactions of the different stoichiometric mixtures of the unmodified GY250 epoxy resin with the aliphatic EH606 and the cycloaliphatic EH637 polyamine adducts were studied using mid FT-IR spectroscopic techniques. As the crosslinking proceeded, the primary amine groups in polyamine adduct are converted to secondary and the tertiary amines. The decrease in the IR band intensity of epoxy groups at about 915 cm(-1), as well as at about 3,056 cm(-1), was observed due to process. Mid IR spectral analysis was used to calculate the content of the epoxy groups as a function of crosslinking time and the crosslinking degree of resin. The amount of all the epoxy species was estimated from IR spectra to changes during the crosslinking kinetics of epichlorhydrin.

AB  - Concrete is a widely used material in the construction industry. It is obtained by mixing cement as a binding agent and inert or only partly reactive aggregates as fillers. In order to increase its bearing power concerning extension it is fitted with steel elements as armature. It is usually believed that the concrete provides the steel armature, embedded into it, with the protection against the corrosion regarding the high alkalinity that takes place during the hydration reactions and which retains as the solution in the concrete pores. Regardless of the aforesaid the corrosion of the steel armature in the concrete occurs due to the effect of a number of factors including the contamination of the concrete by chlorine ions, carbonation of the concrete and the like. As a consequence of this corrosion the formation of corrosion products that are in terms of volume much bigger than the in-built metal takes place and that results in the additional stress to extension of the material of the concrete. As the concrete is weak to strains by extension these forces lead to the occurrence of cracks, detachment and braking away of the concrete cover layer from the armature. Further corrosion that can endanger the lifetime of the entire structure develops on the in-built armature. This problem occurs with the reinforced concrete constructions such as bridges, dams and suchlike. Therefore it is by all means necessary to protect additionally the steel armature in the concrete against the effects of the corrosion. .
AB  - Beton je veoma raširen kao materijal u građevinarstvu. Dobija se mešanjem cementa kao vezivnog sredstva i inertnih ili samo delimično reaktivnih agregata kao punila. Za povećanje njegove nosivosti s obzirom na istezanje u njega se ugrađuju čelični elementi kao armatura. Normalno se smatra da beton pruža zaštitu čeličnoj armaturi koja je u njega ulivena od korozije s obzirom na jaku alkalnost do koje dolazi u toku hidratacionih reakcija i koja se zadržava kao rastvor u porama betona. Bez obzira na izloženo do korozije čelične armature u betonu dolazi usled delovanja više faktora, uključujući kontaminaciju betona hlornim ionom, karbonacijom betona i sl. Usled ove korozije dolazi do stvaranja korozionih produkata koji su zapreminski mnogo veći od ugrađenog metala što dovodi do dodatnog naprezanja na razvlačenje materijala betona. Kako je beton slab na opterećenja, razvlačenjem ove sile dovode do pojave naprslina, odvajanja i otpadanja betonskog prekrivnog sloja sa armature. Na izloženoj armaturi dolazi do dalje korozije, koja može ugroziti vek trajanja cele strukture. Ovaj problem se javlja kod armirano-betonskih konstrukcija kao što su mostovi, brane i sl. .

AB  - The aim of this paper is to analyze scale made from heating drinking water from Belgrade conduit part Vidikovac. The major component of fur (boiler scale) is calcium carbonate, but also there are some other alkali and alkaline (earth) metals (88.35 %) heavy metals (10.71 %), radioactive elements: uranium in concentration of 1,5 ppm or 0.0003 %. There are found in scale and according to that they are in drinking tap water. In test drinking water determined presence of some elements, witch if they are presence in higher concentration in drinking water could cause accumulation effect (for example Hg, Pb). There were detected some elements like Ni, As which haven't been found in arms of Belgrade conduit till now by this method. That shows domain of highly industrial production. For that propose was used for the first time method fractional extraction, was determined that uranium associated mostly with oxides: manganese and iron (74.34 %) totally 98.02 % for the present state potential accessible to humans. This means that in drinking water are natural uranium and uranium in environment made by people. Analysis of scale, with all recognizing parameters of its becoming (flow water, temperature, etc.) is indirect method analyses drinking water quality, specially for low concentration harmful pollutants. .
AB  - Predmet ispitivanja u radu bio je kamenac nastao zagrevanjem vode za piće koja se nalazi u vodovodnoj mreži Beograda - dela grada Vidikovac. Analiza kamenca pokazala je da je njegov glavni sastojak kalcijum-karbonat, ali se, osim kalcijum-karbonata, u kamencu, a sami tim i u vodi za piće nalaze i drugi elementi, osim alkalnih i zemnoalkalnih metala (88,35%), i teški metali (10,71%), polumetali i radioaktivni elementi - uran u koncentraciji od 1,50 ppm (ili 0,0003%). U ispitivanoj vodi za piće utvrđeno je prisustvo nekih elemenata, čije prisustvo u vodi u većoj količini nije poželjno, jer imaju kumulativno dejstvo (npr. Hg, Pb), ali i nekih elemenata koji do sada, ovom metodom, nisu nađeni u granama beogradskog vodovoda, kao što su Ni i As, što ukazuje da se radi o područjima gde je razvijena industrijska proizvodnja. Metodom frakcione ekstrakcije, koja se prvi put korišćena u ove svrhe, utvrđeno je da je uran najviše vezan za okside gvožđa i mangana (74,34%) što u ukupnoj vrednosti od 98,02% predstavlja oblik koji je potencijalno pristupačan ljudskom organizmu. To znači da se u vodi za piće nalazi i prirodni uran ali i uran koji je antropogenim putem došao u životnu sredinu. Analiza kamenca, uz poznavanje svih parametara nastanka kamenca (protok vode, temperatura i dr.), predstavlja posrednu metodu analize kvaliteta vode za piće, posebno za polutante niskih sadržaja štetnih za ljudski organizam.

AB  - Investigations, conducted in this study showed that waste phosphogypsum-dihydrate represents a burden which even must not be kept in deposits because of its large quantity in relation to the main product – phosphoric acid, as well as because of great impact of a phosphogypsum deposit on the environment. By the proposed procedure, calcium-sulphate dehydrate is transformed into a far purer α-hemihydrate which, with its physic-chemical characteristics, approaches natural gypsum and contains additional components which enable formation of small-grain phosphogypsum which may be utilised in construction industry. Test installation, given in this study, is highly automated and designed in such way to be operated by only one person. The obtained α-hemihydrate may be utilised for obtaining of gypsum blocks and dry hemihydrate
