Abstract
Predmet istraživanja ovog rada je sorpcija potencijalno toksičnih metala (Cu2+, Pb2+, Cd2+ i Zn2+) na aluvijalno tlo u blizini vodocrpilišta Stara Loza. Ciljevi rada su: utvrditi fizikalno-kemijske karakteristike tla, utvrditi sorpcijske kapacitete horizonata tla te izraditi sorpcijske izoterme na porušenim uzorcima tla. Tekstura tla je pjeskoviti prah čija je boja svijetlo žuta, a struktura granularna. Najveća gustoća tla određena je u zadnjem horizontu tla što je i očekivano. pH vrijednost tla je u rasponu od 7,97 do 8,38 te ima blago alkalna svojstva. Električna vodljivost ima veće vrijednosti do 80 cm dubine, ali s dubinom ona opada (od 833 do 131 μS/cm) . Slične odlike u tlu ima i kapacitet kationske zamjene (od 23. 21 do 15.97 cmol/kg) gdje su najveće vrijednosti određene do iste dubine. Sorpcijski eksperiment na porušenim uzorcima tla izvodio se koristeći multi elementnu otopinu nitrata bakra, olova, kadmija i cinka. Na temelju rezultata eksperimenta utvrđene su linearne sorpcijske izoterme za sve horizonte, iz kojih su se odredili Freundlich-ovi distribucijski koeficijenti (za koje je utvrđen niz Pb>Cu>Cd>Zn). Usporedbom sorpcijskih izotermi potencijalno toksičnih elemenata kroz profil tla, utvrđeno je da se olovo najbolje sorbira na tlo te da se sa povećanjem dubine sorpcija smanjuje.
Abstract (english)
Abstract: The subject of this thesis is the sorption of potentially toxic metals in Fluvisol near the abandoned water abstraction site Stara Loza. The objectives of this study are to determine: physical-chemical characteristics, sorption capacities of soil horizons, create sorption isotherms on bulk samples. Soil texture is sandy silt which color is light yellow, and structure is granular. The highest bulk density is determined in horizon Gso. pH values of soil varies from 7.97 to 8.38. Electrical conductivity has highest values (from 833 to 191 μS/cm) until 80 cm of depth (horizon IIIC). Cation exchange capacity (CEC) has similar values (23. 21 to 15.97 cmol/kg) until horizon IIIC. Sorption experiment on bulk samples was performed using the multi element solution of copper, lead, cadmium and zinc nitrates. Based on the results of the experiment, linear sorption isotherms were created for all the soil horizons. Freundlich distribution coefficients are determined from sorption isotherms (and their sequence is Pb>Cu>Cd>Zn). The comparison of sorption isotherms of potentially toxic metals through the soil profile has determined that the lead has the best sorption in the soil. Sorption is reducing with depth.
