ABSTRACT

Results of studying adsorption of some heavy metals (Cu²⁺, Cr³⁺, Zn²⁺, Pb²⁺) by bottom sediments and montmorillonite at the presence of humic substances are generalized. Peculiarities of influence of complexation and pH on the adsorption of metals by these sorbents were analyzed. It has been shown that the formation of complex compounds with humic and ful vic acids causes a decrease in adsorption of the metals under study.
