AB  - In the research phase of nuclear materials from the Backa area (NW of Serbia), hydrogeochemical prospecting was applied, which covers an area of about 500 km2. Samples were collected from surface water, from sources and wells, and bores. Combined hydrogeochemical methods included the examination of U, Ra, Pb, Zn, Cu, Mo, Li, Sr; anions HCO3-, SO42-, Cl-; cations Ca2+, Mg2+, Na+, K+, as well as the determination of SiO2, Eh, Ep and pH values. Additional testing determined the water content: NO3, F, Br, J, P. Value content of uranium (U) varied in the range of 0.1 - 125 ppb; Ra 0.026 - 0.33 Bq/l; Rn 1.45 - 32.63 Bq/l. At selected locations the uranium content in the A - horizon (15 - 20 cm) were determined. According to the geological and structural characteristics of the research area, results are shown on the maps in scale of 1:50000 and on appropriate diagrams and tables. The aim of this study was the application of geochemical prospecting method for the identification of geopathogenic zones of the influence of natural radionuclides in the rural settlements environment.

AB  - Hyperalkaline (pH>10.5) springs are extremely rare. There are only about ten in the entire world. This type of water has been identified in an ultramafic massif in central Serbia, on Mt. Studena, during the course of investigations conducted in 2017. The investigations included prospecting, terrain mapping and sampling, followed by assessment of data collected in situ and from laboratory analyses. The hyperalkaline spring is of the ascending type, its yield is very low (~0.05 L/s), and the water emerges in a diffuse fashion along fractures. The spring water is of the Ca-OH type, the pH level is 11.6 and the water temperature 11.2°C. The drainage area of the spring, like the entire Mt. Studena, is built up of Paleozoic ultramafic rocks, which geotectonically belong to the External Vardar Subzone. The spring is situated in the floodplain of the Brezanska River, whose channel is the local base level of erosion. The primary point of groundwater emergence is in solid ultramafic rocks, within a zone of fractures up to 0.5 mm wide, over a land area of ~1.5 m2. The paper describes a conceptual model of the formation of hyperalkaline water for the ascending spring in the ultramafic valley of the Brezanska River, on the northern slopes of Mt. Studena. The pH level of the groundwater is indicative of contemporary serpentinization, deep groundwater circulation and a prolonged contact between groundwater and ultramafic rocks along secondary fracture systems.

Zahtevi ove vrste često prave probleme i ograničavaju razvoj prehrambene i farmaceutske industrije.

AB  - Upotreba natrijum-hidroksida u regeneraciji anjonskih smola, zbog njegove agresivnosti i propisanih zahteva u vezi sa njegovom primenom, nije preporučljiva na postrojenjima malog kapaciteta kao i na postrojenjima za individualnu upotrebu. Na ovim postrojenjima za regeneraciju se preporučuje upotreba natrijum-hlorida, a efekti regeneracije i efikasnost u toku rada se povećavaju korekcijom pH vrednosti sirove vode. Dužom upotrebom anjonske smole dolazi do stvaranja „fouling”-a na smoli, što utiče na smanjenje zapremine prečišćene vode u toku jednog ciklusa rada. pH vrednost utiče na rastvorljivost kao i na proces adsorpcije organskih materija na anjonskoj smoli, usled čega će promena pH vrednosti sirove vode uticati i na promenu zapremine prečišćene vode u toku ciklusa rada. Rezultati ispitivanja ovog uticaja prikazani su u ovom radu.
AB  - Regeneration of anion resins by sodium hydroxide is not recommended for both small capacity plants and facilities for individual use, because of its aggressive nature and mandatory requirements related to its application. In these cases, the use of sodium chloride is recommended for the regeneration. Regeneration effects and work efficiency are increased with the pH correction of raw water. Due to the longer use of anion resin, “fouling“ is formed on the resin, which decreases the volume of water treated within one work cycle. pH value effects solubility and adsorption of natural organic matter on anion resin, so a change of pH of raw water impacts the volume of treated water during work cycle. Results of this influence are presented in this paper.
