Abstract

Some new modified sorbents based on flask of the Astrakhan region, have been obtained. A comparative study of the sorption of cadmium on the sorbents presented has been done. Isotherm static sorption of substances from aqueous solutions have been studied. The change in enthalpy (H), isobaric-isothermal potential (G) and entropy (S) of sorption have been calculated. Kinetics of sorption of cadmium ions from water solutions has been calculated. The results can be used for water purification from cadmium ions.

Keywords

Sorbent, sorption, flocculants, heavy toxic elements, cadmium, water purifying.
