AB  - Preparation of samples by microwave technique consists of large number of phases, from taking samples till receiving homogeneous solution for instrumental analysis. Samples preparation can include combination of drying, wetting, extraction, digestion, analytic separation and solvent removing. The analysis of content of heavy metals in potato from Braničevo Region by the usage of atomic absorption spectrophotometry (AAS) showed that certain samples of potato contain more than 1ppm of lead, and that certain samples contain amount of lead which is even 4 times higher than allowed MDK value. As for cadmium, all samples contains amount which is 7 to even 20 times higher than allowed MDK value. Chrome and nickel are not allowed by Law to be in products for human diet, and by this analysis it is determined that these samples contain chrome (total). In none of these samples was determined the presence of nickel. Received results of the analysis showed that large amounts of chemical (mineral) fertilizers were used at these soils. According to received results it can be concluded that the soil as well as increased usage of phosphate fertilizers are main cause for the presence of heavy metals in potato

AB  - It is estimated that there are more than 550 million road vehicles in the world in everyday use. Annually, 1.3 billion used tyres are dismantled from these vehicles due to safety reasons. A small number of these tyres end up reused as second-hand tyres or, after being retreated, as new ones. The rest are end of life tyres, which are recycled or used as tire derived fuels under controlled combustion conditions. Modern vehicle tyres are a high-technological product containing, on the average, 85% hydrocarbon, 10-15% steel, as well as some other chemical materials. Tyres are high caloric materials, with a calorific value of a passenger car tyre of approximately 30.2 MJ/kg, which is more than of hard coal and comparable to the calorific value of petrol-coke. Having this in mind, many countries use end of life tyres as safe alternative fuel in cement works or power plants. Undeveloped countries dump end of life tyres on legal and illegal scrap stockpiles. End of life tyres, if disposed of correctly, do not endanger the environment because they are chemically inert. However, since they can easily be burnt, there is a real possibility of tyre dump fires, which in effect can lead to harmful products emission that extremely pollute the environment. End of life tyres represent a very important secondary material, which, when recycled, is transformed into a number of raw materials used in rubber industry, for road construction, sports facilities, residential and business buildings, artificial fish habitats in shallow seas, sea walls, steel production, etc. By the industrial procedures of controlled degradation, which have been uneconomical up until now, gaseous and liquid fuel can be obtained by natural rubber, steel and soot recycling. The countries of the EU, together with Norway and Switzerland, were the world leaders in the field of effective end of life tyre management in the year 2009. Out of 2.62 million tonnes of end of life tyres, 95% were restored or used as energents, and 5% settled on dumps. About 26.000 t of used tyres are collected in Serbia each year. In accordance with adopted legal legislations, up to 30% can be used as tire derived fuels while 70% are being recycled. Serbia belongs to the group of countries that have solved the problem of used tyres in a modern way, and in accordance with EU Legislation practice.

AB  - This paper presents the results of investigating the possibilities of zinc recycling out of industrial waste slag, which is formed during the brass production. This secondary contains approximately 50% of zinc, 10% of copper and less amounts of iron, lead, cadmium and chloride, with the aim to examine the possibility of efficient zinc recycling as a part of existing industrial hydrometallurgical process of zinc production, in the plant in Šabac. Previous laboratory investigations of slag valorization by leaching in waste electrolyte (sulphur-acid solution from hydrometallurgical zinc production) proved that leaching efficiency of, approximately, 95% of zinc and 47% of copper, could be reached. The obtained solution has a suitable content so it can be directly included in the already existing hydrometallurgical process of zinc production, with bigger control of chloride content. By industrial experiment of leaching brass slag, laboratory results were confirmed, and on the basis of materials balance established in industrial experiment, high efficiency and economic justification of this treatment was proved. .
AB  - U radu su predstavljeni rezultati ispitivanja mogućnosti recikliranja cinka iz industrijske otpadne šljake koja nastaje u proizvodnji mesinga. Ovaj sekundar sadrži oko 50% cinka, 10% bakra i manje količine gvožđa, olova, kadmijuma i hlorida, a cilj istraživanja je bio da se ispita mogućnost efikasne reciklaže cinka u okviru postojećeg industrijskog hidrometalurškog procesa proizvodnje cinka, u fabrici u Šapcu. Prethodnim laboratorijskim istraživanjem valorizacije šljake luženjem u otpadnom elektrolitu (sumporno-kiselom rastvoru iz hidrometalurške proizvodnje cinka) dokazano je da se dostiže izluživanje cinka od oko 95% i bakra oko 47%. Dobijeni rastvor ima pogodan sastav pa se može direktno uključiti u postojeći hidrometalurški proces proizvodnje cinka. Industrijskim eksperimentom luženja mesingane šljake potvrđeni su ostvareni laboratorijski rezultati, a na bazi materijalnog bilansa zasnovanom na industrijskom eksperimentu dokazana je visoka efikasnost i ekonomska opravdanost ovakvog postupka. .

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. .

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

AB  - Nowadays, due to using many rare metals in the most advanced technologies, the demand for these metals is increasing. Rare metals, however, mostly don’t show the property of creating their own mineral deposits, making their production more complicated. Some rare metals, e.g. gallium, germanium, indium and thallium usually accompany zinc ore. In the procedure of hydrometallurgical zinc production, the concentrating of these metals occurs in some interproduct processes, out of which they can be extracted. The possibility of obtaining rare metals from these sources is directly caused by the contents and quantities in specific interproducts. This paper deals with controlling the distribution of rare metals Ga, Ge, In and Tl in hydrometallurgical zinc production, in zinc plant Chemical Industry „Zorka„ in Šabac, in order to determine the places and concentration level of controlled rare metals. It is determined that In and Ga are significantly concentrated in specific output mud and precipitates from the process, and that they exist in commercially significant quantities on existing depots of these materials, while it is not the case for Ga and Tl.

AB  - This paper presents the experimental results of the extraction of lead and silver from a lead-silver waste cake obtained in the process of hydrometallurgical zinc production. While controlling the pH value, the lead-silver cake was leached at a temperature close to boiling point in different concentrations of aqueous calcium chloride solutions. The experiments were performed applying different ratios between the mass of cake and the volume of the leaching agent under different durations of the process. It was concluded that at the optimal process parameters (pH 2.0-2.5; CaCl2 concentration, 3.6 mol dm(-3); temperature, 95 degrees C; solid/liquid ratio, 1:5), the leaching efficiency of lead and silver could reach the approximate value of 94 %. Applying the same optimal process parameters, the method was applied to the leaching of a lead-silver cake in a magnesium chloride solution, but with significantly lower efficiencies. The results show that leaching of lead and silver in a calcium chloride solution could be a prospective method for increasing the recovery of lead and silver during hydrometallurgical zinc production.

AB  - Sulphuric acid is produced by processing iron disulphide ore, through a set of interconnected technological operations, all the chemical processes, and partly the physical ones, being exothermic, taking place with the release of considerable amounts of heat. A great deal of the reaction heat of iron disulphide combustion (about 48%) is used for obtaining aqueous vapor whereas the larger remaining amount is irreversibly wasted or dissipated. Since the released amount of heat may also have a notable impact on the environment, the objective of the research work has been to study the utilization possibilities of waste heat, whereby a double goal could be achieved: the impact of waste heat on the environment would be eliminated and the waste heat could be used for warming up commercial facilities. It is economically justified to exploit the unused waste heat from drying and absorption processes (approximately 69%). This research project includes the utilization of the reaction heat of SO3 absorption for heating industrial and boiler water and for warming up greenhouses. Investment in projects for the utilization of the waste heat from the sulphuric acid plants is economically right and with regard to energy price rise it will be increasingly cost-effective.

Veliki deo reakcione toplote sagorevanja pirita (oko 48%) iskorišćen je za dobijanje vodene pare, dok se veći preostali deo nepovratno gubi ili rasipa. Kako oslobađena količina toplote može imati i veliki uticaj na životnu sredinu, cilj rada bio je da se analiziraju mogućnosti iskorišćenja otpadne toplote, čime bi se postigao dvostruki cilj: eliminisao bi se uticaj otpadne toplote na životnu sredinu a otpadna toplota iskoristila bi se za zagrevanje komercijalnih postrojenja. Ekonomski opravdano je iskorišćenje dela neutilizovane otpadne toplote sa sušenja i apsorpcije (oko 69%). Ovim projektom obuhvaćeno je iskorišćenje reakcione toplote apsoropcije SO3 za grejanje industrijske i kotlovske vode i zagrevanje staklenika. Investiranje u projekte iskorišćenja otpadne toplote iz postrojenja sumporne kiseline je ekonomski opravdano a s obzirom na rast cena energije biće sve ekonomičnije.

AB  - In this paper are showed the results of valorisation of gallium, that is gallium salt gallium(III) chloride, GaCl3, by adsorption with chelate resin and then by extraction with 1, 5 mol/dm3 HCI to GaCl3. The efficiency of used chelate resin adsorption was given which is ca. 10%, while the extraction with HCI is almost completed. In the paper is also presented a mini semi-industrial process of GaCl3 valorisation and there is given the possible block schema of metal gallium receiving from acidic zinc ' liquor.
AB  - U ovom radu prikazani su rezultati valorizacije galijuma, odnosno galijumove soli GaCl3, adsorpcijom Ga2O3 sa helatnim smolama a zatim ekstrakcijom sa 1, 5 mol/dm3 HCl do GaCl3. Data je efikasnost adsorpcije korišćenih helatnih smola koja je oko 10%, dok je ekstrakcija sa HCl skoro potpuna. U radu je prezentirano i mini poluindustrijsko postrojenje valorizacije GaCl3 i data je moguća blok šema dobijanja metalnog galijuma iz kiselog cinkovog luga.

Performed testings point to the structure complexility and phosphogypsum composition while the electron microscope’s pictures showed a different crystal phosphogypsum composition comparing to the natural gypsum. In order to use the waste material of phosphogypsum it must be refined and calcined because of a great number of uncleanesses, the soutce of raw-material and because of a chemical way of producing. By expecting procedure of refinery the radionuclides content stays approximately the same, but it approaches to the natural gypsum because of its physico-chemical characteristics. A stable shape of phosphogypsum α-chemihydrate is got by a longer drying on the temperature of 105°C and it is very similar to the natural gypsum because of its physico-chemical characteristics. As the presence of some uncleanesses isn’t limited for the further use, the phosphogypsum refined in this way, by futher particles reducing to the size of ca. 100 μm, shows as adequate substitute for the natural gypsum. The calcined and refined phosphogypsum can be used for partion walls producing. To avoid the danger of possible radionuclides presence it is better to use the mixture of natural gypsum and phosphogypsum for this production. A great saving of materials and economic effect can be carried out in this way.

AB  - This paper shows the result of examining lead, silver cadmium and copper extraction from lead-silver waste cake in the process of hydrometallurgical zinc production. Besides controlling of pH value, the lead-silver cake was leached at high temperature in calcium-chloride aqueous solution of different concentrations, different relations of cake quantities and leaching agent volume and different process duration time. It was noted that, at optimal chosen process parameters, the following can be extracted: approx. 95% of lead and silver, approx. 50% of copper and cadmium, and approx. 40% of zinc. The results show that chloride leaching can be a prospective method for increasing utilization of useful metals in the process of hydrometallurgical zinc production.

If hydrogen overpotential on the given metal is high, then the rate of overall process is defined by reaction of hydrogen ion reduction. This study investigated the possibility of accelerated dissolving of metal zinc in sulphuric acid by introducing copper cathode on which evolving hydrogen is much easier than on zinc. It was found out that the acceleration of zinc dissolving is possible and, at constant surface of copper cathode depends on the quality of electrical contact between copper electrode and zinc.

AB  - Polarization techniques are used for testing the impact of different compounds (additives) on tinplate corrosion, using pieces of apricot dipped in syrup with and without nitrate addition as electrolyte solution, at the same time using filled cans as electrolytic cell and operating electrode. This procedure determined the intensity of inhibiting tin dissolving with some of the used additives like sodium-benzoate, potassium-sorbate sodium-lauril-sulphate and p-aminobenzoate acid. Adding these additives to canned pieces of apricot in syrup led to inhibiting of tin dissolving, which was experimentally proved.

Ovim postupkom je određena jačina inhibiranja rastvaranja kalaja nekim od primenjenih aditiva, kao što su: natrijum-benzoat, kalijum-sorbat, natrijum-lauril-sulfat i p-amino-benzoeva kiselina. Dodatkom ovih aditiva u konzervisane komade kajsije u sirupu došlo je do inhibiranja rastvaranja kalaja što je eksperimentalnim putem i dokazano.

This procedure determined the intensity of inhibiting tin dissolving with some of the used additives like sodium-benzoate, potassium-sorbate sodium-lauril-sulphate and p-aminobenzoate acid. Adding these additives to canned pieces of apricot in syrup led to inhibiting of tin dissolving, which was experimentally proved., Primenom polarizacionih tehnika ispitivan je uticaj različitih supstanci (aditiva) na koroziju belog lima od kojeg su napravljene limenke primenjujući kao rastvor elektrolita komade kajsije u sirupu sa i bez dodatka nitrata, uz istovremeno korišćenje napunjene konzerve kao elektrolitičke ćelije i kao radne elektrode.

AB  - This paper shows the results of investigations of corrosion resistance of different samples of chromium-nickel steels Č 4574 and Č 4583 in calcium-hypochlorite solution, by potentiodynamic method. The paper presents continuation of investigations on steels URANUS B6 and Č 4578 published in reference [1]. In this paper comparison of the obtained results is carried out, too, in order to detect steel, which quality is the best choice for calcium hypo chlorite solution requirements.
