AB  - Two samples collected from the phosphogypsum deposits of the chemical products industry Elixir Prahovo (Serbia) were subjected to a recrystallization experiment performed over several repeated cycles. In these tests, phosphogypsum was separated into recrystallized (purified) gypsum, insoluble residue and supernatant. Both raw phosphogypsum and recrystallized gypsum were examined using inductively coupled plasma optical emission spectrometry, X-ray diffraction and scanning electron microscopy with energy-dispersive spectrometry. The activity concentrations of (238)u, (235)u, Ra-226, Pb-210,Th- 232 and 40 K were investigated using gamma-ray spectrometry. Based on the activity concentration results, a number of radiometric parameters were calculated for the original and recrystallized phosphogypsum (i.e. radium equivalent activity, y indices for construction materials, a index and external and internal hazard indices). Raw phosphogypsum samples showed greater mean activity concentration levels of U-238 and Ra-226 than the international recommended limits, while the recrystallized gypsum demonstrated notably lower activity concentrations for these two isotopes. The activity concentration of Ra-226 in recrystallized gypsum is similar to 6 times lower than in raw phosphogypsum. Therefore, recrystallized gypsum does not present a radiation hazard when used as a building material, while raw phosphogypsum meets the requirements only for road construction materials.

AB  - This study focuses on the mineralogical characterization of four raw clay samples from Dobrodo deposit, Serbia. Several analytical methods were applied to determine the chemical and mineralogical composition, morphology and physical properties (colour, plasticity, specific surface area, particle size and cation-exchange capacity) of the clay samples. Kaolinite, smectite and illite are the predominant phases in all of the samples studied that contain between 60.2 and 87.1 wt.% of clay. Quartz, feldspars, paragonite and Ti- and Fe-bearing phases were also identified. The relatively high SiO2/Al2O3 mass ratio indicates abundant quartz. The cation-exchange capacity of the samples varied between low and moderately charged clay minerals (12-52 mmol 100 g(-1)) with specific surface area values ranging from 94 to 410 m(2) g(-1). The plasticity index values (11-23%) suggest low to moderate plasticity. Preliminary results show that most of the raw clay from Dobrodo deposit might be suitable for use in ceramic applications.

AB  - The results presented in this paper show an impact of the concentration of the aromatic organic cation on the adsorption of acetochlor on the surface of the organic-modified montmorillonite. Natural montmorillonite from Bogovina (Boljevac municipality, Serbia) was used for organic modification in this experiment. Cation exchange capacity of this montmorillonite (86mmol 100g(-1) of clay) was determined using the methylene blue method. In pretreatment, montmorillonite was modified with NaCl. For the purpose of organic modification, three different concentrations of phenyltrimethylammonium chloride (PTMA) have been selected, based on calculated CEC value: 43mmol 100g(-1) of clay (0.5 CEC), 86mmol 100g(-1) of clay (1 CEC) and 129mmol 100g(-1) of clay (1.5 CEC). The changes in the properties of the inorganic and organic modified montmorillonite were examined using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and batch equilibrium method. Freundlich coefficients show higher uptake of the herbicide by montmorillonite modified with PTMA, compared to inorganic-modified montmorillonite. The results also indicate the influence of the organic cation concentration on the adsorption of the selected herbicide.

AB  - Efficiency of inorganic and organic modified montmorillonites from Bogovina for sorption of the S-metolachlor and clomazone was determined using batch adsorption method. Montmorillonite samples were pretreated with NaCl solution and then with different concentrations of organic complexes. Adsorption isotherms were measured by treatment of the samples with different concentrations of herbicide. Detailed mineralogical characterization of samples was performed using the X-ray diffraction method. Results of interaction between organic complexes and herbicides were obtained using X-ray diffraction, optical, thermal and spectroscopic analysis. Based on the results obtained using X-ray diffraction, it was concluded that all examined organic complexes and herbicides intercalated into interlayer space of montmorillonite. Montmorillonites modified with HDTMA complex exhibited monolayer, bilayer and pseudotrilayer arrangement of HDTMA+ cations in interlayer space, depending on degree of saturation. It has been found that the HDTMA+ cations are forming the partition phase for the herbicide on the surface of the montmorillonite. On the other hand, montmorillonite modified with PTMA complex exhibited monolayer arrangement of cations on the surface of montmorillonite in such a way that the cations act as pillars in interlayer space. The molecules of herbicides in this case were adsorbed on the surface of the montmorillonite. Which functional groups were involved in bonding processes between montmorillonite, organic complex and herbicide best describes infrared spectroscopy. High sorption of examined herbicides on some organic modified montmorillonites creates an opportunity for application of these substrates as potentially useful material for removal of S-metolachlor and clomazone from the environment.

AB  - This study focuses on the mineralogical and thermal properties of clay from "Slatina" deposit, Ub, Serbia. Sampled clays were analysed by XRD, IR spectroscopy, ICP-OES, DTA, specific surface area (SSA), cationic exchange capacity (CEC), gravimetric and grain size measurements. Results show that the studied samples have a medium content of smectite-illite minerals with smaller amount of kaolinite together with quartz, feldspars and goethite. They consist generally of fine particles with medium to high plasticity. Based on their mineral composition and physical properties (grain size, plasticity, CEC) the clays are suitable as raw material for the ceramics industry.

AB  - This study was undertaken to determine the impact of the organic complex concentration on the adsorption of herbicide (acetochlor) at the surface of the organic modified montmorillonite. In this work, natural montmorillonite from Bogovina (Boljevac municipality, Serbia) was used for organic modification. Cation-exchange capacity of this montmorillonite was determined using a methylene blue method (86mmol/100g of clay). Montmorillonite has been modified first with NaCl and then with hexadecyltrimethylammonium bromide (HDTMA-bromide) organic complex. Saturation of cation exchange capacity (CEC) was 50%, 100%, and 150%. Changes in the properties of the inorganic and organic montmorillonite have been examined using the X-ray diffraction, Fourier transform infrared spectroscopy, and batch equilibrium method. Montmorillonite modified with HDTMA-bromide demonstrated higher uptake of the herbicide, compared to the inorganic montmorillonite. Comparing the values Freundlich coefficients in batch equilibrium method, it can be seen that the adsorption of acetochlor decreased in the series: 0.5 CEC HM > 1 CEC HM > 1.5 CEC HM > NaM.

Montmorillonite modified with HDTMA-bromide demonstrated higher uptake of the herbicide, compared to the inorganic montmorillonite. Comparing the values Freundlich coefficients in batch equilibrium method, it can be seen that the adsorption of acetochlor decreased in the series: 0.5 CEC HM > 1 CEC HM > 1.5 CEC HM > NaM.",

AB  - Results presented in this paper are pioneering attempt toward better understanding of the thermal stability of acetochlor sorption in inorganic and organic montmorillonites. Changes in surface properties of acetochlor adsorbed on montmorillonites and montmorillonites modified with hexadecyltrimethylammonium bromide have been investigated by thermogravimetry, derivative thermogravimetry and infrared spectroscopy. The mass loss, as a result of the heating treatment, indicates release of free water, transformation of hydrophilic to hydrophobic surface, the release of acetochlor sorbed on the montmorillonite, the release of acetochlor sorbed on the montmorillonite and dehydroxylation of the structural OH units.

AB  - The results of sorption of acetochlor herbicide with different concentrations (1-15 mu g/mL) in inorganic- and organic-modified bentonite are presented. Acetochlor sorption in both bentonite types was studied by attenuated total reflectance spectroscopy in the mid-infrared region and by batch equilibrium method. Infrared spectroscopy results suggest that the interaction of acetochlor with inorganic (or organic) bentonite takes place by mechanism involving the carbonyl stretching vibration and phenyl ring in the acetochlor molecule. The increase of the acetochlor concentration results in red shift of both corresponding band wavenumbers. Batch adsorption study pointed out more expressed sorption of acetochlor in organic bentonite.

AB  - The paper addresses the issue of health risk associated with the presence of chrysotile in the soil type ranker formed on massive serpentines occurring in the area of Bubanj Potok, a settlement located in the southern Belgrade environs, Serbia. Characterization of the ranker soil was conducted by scanning electron microscopy, X-ray diffraction, micro-Raman spectroscopy and transmission 57Fe Mössbauer spectroscopy. Scanning electron microscopy figures showed regular shaped smectite (montmorillonite) particles, aggregates of chlorite, and elongated sheets of serpentines minerals antigorite. X-ray diffraction analysis confirmed the presence of detrital mineral quartz polymorph as well as minor amounts of other mineral species. Micro-Raman spectroscopy identified the presence of dominant minerals, such as montmorillonite, kaolinite, muscovite, gypsum, calcite, albite, amphiboles (hornblende/kaersutite) and orthoclase. Important polymorph silica modifications of quartz, olivine (forsterite), pyroxene (enstatite/ferrosilite, diopside/hedenbergite), and serpentine (antigorite/lizardite/chrysotile) were identified.
AB  - Rad se bavi pitanjem zdravstvenog rizika povezanog sa prisustvom hrizotila u rankeru (tip zemljišta) formiranom na masivnom serpentinitu u oblasti Bubanj Potoka, naselju koje se nalazi u južnoj okolini Beograda. Karakterizacija rankera je izvršena skenirajućom elektronskom mikroskopijom, rendgenskom difrakcijom praha, mikro-Raman spektroskopijom i transmisionom 57Fe Mesbauer spektroskopijom. Slike dobijene skenirajućim elektronskim mikroskopom pokazuju čestice smektita regularnog oblika montmorionita, agregata hlorita i izdužene listove serpentinskog minerala antigorita. Rendgenska difrakciona analiza potvrdila je prisustvo detrital minerala kvarcnog polimorfa kao i manje količine drugih mineralnih vrsta. Mikro-Raman spektroskopija identifikovala je prisustvo dominantnih minerala, kao što su montmorionit i kaolinit, muskovit, gips, kalcit, albit, amfibol (kaersutit/hornblenda) i ortoklas. Važni polimorfi silika modifikacije kvarca, olivina (forsterit), piroksena (enstatit, ferosilit, hedenbergit, diopsid), i serpentina (antigorit, lizardit, hrizotil) su bili identifikovani.
