摘要：
Some new modified sorbents based on opoka from Astrakhan region were obtained. A comparative study of the sorption of cadmium ions on the surfaces of the sorbents was made. Also the static adsorption isotherm of substances from aqueous solutions was studied. The change of enthalpy, isobaric-isothermal potential and entropy of sorption and kinetics of cadmium ions sorption from water solutions were calculated. The results of the study can be used for the water purification from cadmium ions.
