The sorption mechanism of cadmium ions on the modified fen peat is investigated. kinetic, equilibrium, and thermodynamic parameters process are calculated; kinetic equations diffusion model described. It shown that absorption from an aqueous solution carried out by two centers follows Langmuir law; diffusional described anti-Yander model.
