Abstract
The process of adsorption of ions of heavy metals Cu2+, Pb2+, Zn2+, Cd2+ from aqueous solutions with the mineral adsorbent burnt solid was investigated. Kinetic data on the adsorption process were obtained. Parameters of adsorption equilibrium using the Langmuir and Dubinin–Radushkevich equations have been calculated. The efficiency of extracting heavy metal ions upon modification of the adsorbent and in the area of low concentrations is shown.
