Abstract

The article provides research on testing natural sorbents based on peat, diatomite and vermiculite during the adsorption of heavy metal ions (Pb, As, Cr, Cr6+, Cr3+, Cu). The following series of sorbents has been formed according to the efficiency of adsorption of heavy metal ions from aqueous solutions of salts: peat - granular diatomite> coarse vermicu-lite> medium fraction vermiculite> peat - non-granular diatomite> diatomite. Key words: natural sorbents, ameliorants, disturbed lands, heavy metals, adsorption, recultivation, bioremediation.
