The new modified sorbents on the basis of the mould boxes of the Astrakhan region. A comparative study of the adsorption of cadmium in the sorbents. Studied isotherms static sorption of substances from aqueous solutions were calculated enthalpy change (О”Рќ), the isobaric-isothermal potential (О”G) and entropy (О”S) sorption. Calculated kinetics of sorbtion cadmium ions from water solutions. Results of work can be used for purification of water from ions of cadmium.

Key words: Sorbent, Sorption, Flocculants, Heavy toxic elements, Cadmium, Clean water.
