AB  - The aim of this article is the determination of uranium accumulation in plants tissue in shoots and roots of corn-maize (Zea mays), grown on two types of soils, pseudogley and chernozem, together with its phytotoxic effect on the plant growth and development. The soils was contaminated with different rates (10 to 1,000 mg U(VI) kg(-1)) of uranyl nitrate (UO2(NO3)(2)center dot 6H(2)O). Vegetative tests performed with maize indicated uranium phytotoxic effect on plant height, yield, and germination of seeds. This effect was stronger on the plants grown on pseudogley in comparison with those grown on chernozem. Soil properties determined the tolerance and accumulation of U in plants. A linear dependence between the content of uranium in soil and in plants tissue, including maximal content of 1,000 mg U kg(-1), indicates that maize could be used for phytoremediation of uranium-contaminated soils.

AB  - U ovom radu prikazani su rezultati ispitivanja adsorpcije uranil-jona na zeolitskom mineralu klinoptilolitu modifikovanom tretmanom kiselinama. Adsorpcija je praćena pri različitim količinama čvrste faze u suspenziji kao i na različitim pH. Modifikacija je izvršena tretiranjem klinoptilolita sa kiselinama: hlorovodoničnom, oksalnom i limunskom. Polazni i modifikovani klinoptiloliti su okarakterisani termičkom analizom (DTA/TGA), određivanjem hemijskog sastava i određivanjem sadržaja izmenljivih katjona, dok su polazne kao i neadsorbovane količine uranil-jona određivane fluorimetrijskom metodom. Određeno je da je adsorpcija niska na prirodnom zeolitskom mineralu, dok kiselinski tretman značajno povećava adsorpciju uranil-jona. Kod kiselinski tretiranih klinoptilolita najviši indeksi adsorpcije uranil-jona su postignuti na uzorku dobijenom modifikacijom sa hlorovodoničnom kiselinom.
AB  - In this paper, the results of adsorption of uranyl ion on acid-modified zeolitic mineral clinoptilolite are presented. Adsorption was investigated at different amounts of solid phase in suspension, as well as at different pH values. The modified clinoptilolite samples were obtained by treatment of clinoptilolite with acids: hydrochloric, oxalyc and citric. Starting and modified clinoptilolites were characterized by chemical analysis, thermal (DT/TG) analysis and by determination of cation exchange capacity, while starting and nonadsorbed amounts of uranyl ion were determined by fluorometric method. Uranyl ion adsorption experiments on natural unmodified zeolitic mineral showed that uranyl ion adsorption was low (29.2%) and that treatment of clinoptilolite with acids significantly increases the adsorption of uranyl ion (>90%). In the case of acid treated clinoptilolites, the highest adsorption of uranyl ion was achieved on clinoptilolite modified with hydrochloric acid. Kinetics of adsorption showed that adsorption of uranyl ion begins very fast and that the most of uranyl ion was adsorbed in first 30 min. Practically, there were no changes in uranyl ion adsorption within next 72 h.

AB  - U radu su prikazani rezultati modifikovanja površine kalcita suvim i mokrim postupkom. Kalcit je glavni i najzastupljeniji mineral kod prirodnog krečnjaka (>95%). Ispitivanja su vršena na seriji uzoraka sa sadržajem stearinske kiseline , kao površinski aktivne materije, od 0,5, 1, 1.5, 2, 3 i 4%. Na proizvodima dobijenim suvim i mokrim postupkom modifikovanja urađena je diferencijalno termijska analiza (DTA), termo-gravimetrijska analiza (TG) i skenirajuća elektronska mikroskopija (SEM). Stepen hidrofobnosti uzoraka praćen je određivanjem indeksa obloženosti. Rezultati pokazuju da je kod mokrog postupka najveći indeks obloženosti od 99,9% dobijen je na uzorku sa sadržajem stearinske kiseline od 1,5%, a kod suvog postupka kod uzorka sa sadržajem stearinske kiseline od 3%. Rezultati termičke analize pokazuju da se osnovni egzotermni maksimum kod oba postupka javlja na približno istim temperaturama (>310°C) što ukazuje na postojanje istih aktivnih mesta na površini kalcita na kojima može biti hemisorbovana stearinska kiselina. Položaj i intenzitet ostalih egzotermnih pikova ukazuje na različito vezivanje stearinske kiseline za površinu kalcita kod mokrog i suvog postupka.
AB  - In order to obtain hydrophobic material, the surface of natural limestone with the high content of calcite (>95%), was treated with 0.5, 1, 1.5, 2, 3 and 4% of stearic acid. Two methods were used for modification: the solution method and the dry coating. The obtained products were characterized using the thermal analysis (DT/TG), X-ray powder diffraction analysis (XRPD), scanning electron microscopy (SEM) and by the evaluation of floating test. Results of floating test showed that when the solution method was applied, the hydrophobicity arrived at above 99% when the amount of stearic acid was 1.5%, while with the dry coating the same hydrophobicity was achieved with 3% of stearic acid. From the position of the principal exothermic peak (> 310°C) at DTA curves, for calcites modified with dry coating and with the solution method, it can be concluded that with both modification processes, the same active sites exist at the calcite surface onto which stearic acid may be chemisorbed. However, the position and the intensity of the other exothermic peaks, indicate the differences in bonding of stearic acid at the calcite surface during the solution method and the dry coating.

AB  - Uranium is a radiotoxic and chemotoxic heavy metal. Uptake and accumulation of U has been studied in plants native to uranium mine sites, but not in cultivated plants which are commonly consumed by humans. The objective of this study was better understanding of U uptake and accumulation in cultivated plants and whether different contents of uranium (U) in the substrate affect its concentration in plants and their dry matter mass. Two substrate variants for growing plants, which differed in the uranium content: solid wastes (tailings) and tailings mixed with sand (w/w 1:1). Large amounts of solid wastes (tailings) resulting from the exploitation and treatment of uranium ore from the closed uranium mine Gabrovnica-Kalna, on southeast of Serbia, contained generally 15.33 mg U/kg. In the experiment, three plant species (corn NSSC 231, sunflower N.S. Dukat, and green peas Smederevska Palanka) were grown in pots on the four substrate variants during 40 days. Substrate was suffused by drinking water (DW) and "uranium water" (UW), which issue out from the mine, contained 0,053 mg U/ dm(3). Obtained results show that when UW was added to tailing concentration of U in plants increased. When the content of U in the substrate was lowered by adding sand, the concentration of U in plants decreased, though was significantly higher in comparison to the variants to which DW was added. Dry matter mass was higher in variants where UW was used. Concentration of U was significantly higher in root than in above-ground parts.

AB  - Phosphate-induced metal stabilization (PIMS) using apatite stabilizes uranium in situ, by chemically binding it into the new low-solubility (Ksp=10-49) phase. Uranium-phosphate-autunite is stable across a wide range of geological conditions for millions of years. A large area of contaminated soil is suitable for in situ remediation that involves minimizing the mobility of the uranium. Laboratory study was conducted to quantify different forms of apatite sequestration of uranium contaminant. The experiment was done with natural phosphate from Lisina deposit (14.43 % P2O5), with non-treated samples, phosphate concentrate samples with 34.95 % P2O5 and mechanochemically activated of natural apatite. Different concentration of P2O5 in apatite, pH, reaction time, solid/liquid ratio was investigated. The concentrate at pH 5.5 for 7 days sorbed around 93,64 % and nature apatite, with 14,43 % P2O5, for 30 days sorbed 94.54 % of the uranium from the water solution, concentration 100 µg U/ml. The results show that mineral apatite 'Lisina' is very effective for the treatment of contaminated soils in situ immobilization of U. Mechanochemical activation of natural apatite in vibration mill immobilized 85.37 % of uranium in the 7-day period of acting. This research on natural apatite from the deposit 'Lisina' for immobilization of uranium was the first one of this type in our country.

AB  - Arsen se pojavljuje kao prateći element sulfidnih ruda ležišta gvožđa, olova i drugih metala. Njegovo prisustvo u rudama je katkad u dovoljnim količinama da je ekonomski opravdano razmišljati o njegovoj eksploataciji. Kao toksičan element i u veoma malim količinama degradira kvalitet rude, na primer olovo-cinkane rude ili rude zeolita. U mnogim geološko-geohemijskim sistemima je prisutan arsen, koji predstavlja rizik za kvalitet životne sredine. Ispitivan je uticaj različitih postupaka hemijskog razlaganja uzorka mineralne sirovine na određivanje arsena, metodom AAS-MHS, sa ciljem da se na bazi eksperimentalnih rezultata, odabere najoptimalniji. Postupak treba da omogući efikasno hemijsko razlaganje uzorka, odnosno transformaciju iz čvrstog u tečno i potpunu jonizaciju migrirajućeg atoma ili jona arsena, što predstavlja osnovu za njegovo kvantitativno određivanje. U eksperimentima je korišćen prirodni zeolit i njemu identična po hemijskom sastavu napravljena smeša (kao referentni materijal) sa određenom koncentracijom arsena.

AB  - Arsenic occurs as a concomitant element of sulfide iron, lead and other metallic ores. The presence of arsenic in ores is sometimes in the quantities sufficient to be economically feasible. As a toxic element, even in the small quantities, arsenic degrades the quality of the ore, for example the lead-zinc or zeolite ore. Moreover, the arsenic is present in many geological-geochemical systems, representing the considerable risk for the quality of the environment. The objective of this paper is to present the results of the investigation aimed to evaluate the influence of different procedures applied for chemical destruction of mineral raw material on arsenic determination, using AAS-MHS method and selection of the optimal sample preparation procedure. The selected procedure should provide the efficient destruction of the sample, meaning transformation from solids to liquid, and total ionization of migrating atom or ion of arsenic, which is the basis for its quantitative determination. Natural zeolite ore and chemically identical zeolite mixture (reference material), with the adequate concentration of arsenic were used in the experimental work. The most appropriate procedure for chemical destruction can be preferentially and successfully applied also to the other mineral materials and tailings in which arsenic should be determined.

AB  - U radu je ispitivana adsorpcija uranijum(VI)-jona na površinski modifikovanom hejlanditsko/klinoptilolitskom zeolitskom tufu (organozeolitu). Organozeoliti su dobijeni jonskom izmenom neorganskih katjona sa površine zeolita sa heksadecil trimetil amonijum (HDTMA) jonima. Dobijeni rezultati su pokazali da je adsorpcija uranijum(VI)-jona na nemodifikovanom zeolitskom tufu niska (indeks adsorpcije 35% odnosno 0,34 mg uranijum(VI)-jona/g adsorbenta), dok kod organozeolita, adsorpcija uranijum(VI)-jona raste sa porastom sadržaja HDTMA na površini hejlandita/klinoptilolita. Najviši indeksi adsorpcije su dobijeni na organozeolitu od kojeg su svi katjoni sa spoljašnje površine zamenjeni sa HDTMA(OA.-10). Ispitivanja adsorpcije uranijum(VI)-jona na organozeolitu OA-10, na različitim pH su pokazala da adsorpcija raste sa porastom sadržaja adsorbenta u suspenziji. Kako oblik uranijum(VI)-jona u rastvoru, zavisi od pH sredine, isti oblik adsorpcionih izotermi na pH 6 i 8 (Langmuir-ov tip izoterme), ukazuje da se uranijum(VI)-jon u istom obliku apsorbuje na površini zeolitskog tufa. Adsorpcija uranijum(VI)-jona pri pH 3 odgovara Tipu III adsorpcione izoterme.
AB  - The adsorption of uranium(VI) on heulandite/clinoptilolite rich zeolitic tuff modified with different amounts (2, 5 and 10 meq/100 g) of hexadecyltrimethyl ammonium (HDTMA) ion was investigated. The organozeolites were prepared by ion exchange of inorganic cations at the zeolite surface with HDTMA ions, and the three prepared samples were denoted as OA-2, OA-5 and OA-10. The maximal amount of HDTMAin the organozeolite OA-10 (10 meq/100 g) was equal to the external cation exchange capacity of the starting material. The results showed that uranium( VI) adsorption on unmodified zeolitic tuff was low (0.34 mg uranium(VI)/g adsorbent), while for the organozeolites, the adsorption increased with increasing amount of HDTMA at the zeolitic surface. The highest adsorption indexes were achieved for the organozeolite OA-10, in which all the surface inorganic cations had been replaced with HDTMA. An investigation of the adsorption of uranium(VI) ions onto organozeolite OA-10 at different pH values (3, 6 and 8) showed that the adsorption index increased with increasing amount of adsorbent in the suspension. Since uranium(VI) speciation is highly dependent on pH, from the adsorption isotherms, it can be seen that uranium(VI) adsorption on organozeolite OA-10 at pH 6 and 8 is well described by a Langmuir type of isotherm, while at pH 3, it corresponds to a Type III isotherm.
