Abstract

Multisorption of heavy metals from aqueous solutions is very important in hydrometallurgy, industrial waste disposal, and water purification. The aim of this study is Monte Carlo simulation of the adsorption process of the Cd2+, Pb2+, Zn2+ ions on the SiO2, Al2O3 sorbents impregnated with organic ligands (dithizone, PAN, benzothiazole). The impregnated alumina has a multisorption capacity, and silicon oxide impregnated by dithizone exhibits high selectivity to cadmium ions. The calculated data on the adsorption energy good correlate with the experimental data on multisorption activity of impregnated sorbents.
