Abstract

Predmet istraživanja ovog rada je sorpcija bakra na aluvijalno tlo iz okolice naselja Kosnica, te simulacija transporta bakra uz pomoć programa HYDRUS 1D. Ciljevi rada su: utvrditi sorpcijski kapacitet pojedinog horizonta tla, te izraditi sorpcijske izoterme bakra na porušenim uzorcima u laboratoriju; pomoću dobivenih koeficijenata distribucije i podataka o oborinama modelirati ponašanje bakra u tlu u slučaju akcidentne situacije izlijevanja 1000 mg/l (1 mg/cm3) otopine bakra. Eksperiment sorpcije bakra na porušenim uzorcima izrađen je koristeći otopinu modre galice (CuSO4*5H2O) u različitim koncentracijama. Na temelju dobivenih podataka izvršeno je modeliranje vertikalnog transporta otopine bakra kroz pedološki profil dubine 210 cm. Utvrđena je linearna izoterma za sve horizonte tla, sa koeficijentima korelacije iznad 0,99. Najveći koeficijent distribucije određen je u najplićem horizontu A i iznosi 85,923. Modeliranjem u programu HYDRUS 1D utvrđeno je da oko 1% početne koncentracije dolazi do vodnog lica, što kod većih koncentracija onečišćivala može biti iznad MDK u vodi za piće.

Abstract: The subject of this research is sorption of copper on alluvial soil from the vicinity of the village Kosnica and simulation of copper transport with the program HYDRUS 1D. The objectives of the study are to determine the sorption capacity of each soil horizon, and create sorption isotherms of copper on bulk samples in the laboratory; and using the obtained coefficients of distribution and data on precipitation to model transport of copper through soil profile in case of accidents (spilling 1000 mg/l (1 mg/cm3) solution of copper). Sorption experiment of copper on bulk samples are made using a solution of blue vitriol (CuSO4 * 5H2O) in different concentrations. Modeling of copper transport solution through soil profile (depth of 210 cm) was made based on obtained data. For all soil horizons was determined linear isotherms, with correlation coefficients above 0.99. The highest distribution coefficient was determined in the shallowest horizon and the amount was 85.92. Modeling with HYDRUS 1D revealed that about 1% of copper concentration of the water reaches the water table, which may be above the maximum allowed concentration in drinking water.
