Kinetic laws of sorption of cobalt (Co²) and cadmium (Cd²⁺) ions from water solutions modeling composition of industrial liquid wastes on Na-clinoptilolite, Na-bentonite and synthetic ion exchange cationite КУ-2-8 on H- and Na-forms have been studied. A number of basic kinetic parameters have been experimentally calculated in the process of sorption and mixed diffusion. The results of investigating kinetics of sorption process from solutions permitted to expose the factors that condition the process proceeding rate.
