The equilibrium condition and kinetics of the sorption of Cu2+, Zn2+, Cd2+ and Pb2+ ions with Amberlite IRC 748 (with iminodiacetic group, Na+), Duolite C 467 (with amino-fosfon group, Na+), Dowex MAC-3 (with carboxyl group, H+) and Amberlite IR 120 (with sulpho-group, H+) cationites have been studied and thermodynamic parameters of the processes have been calculated on the basis of data gained from the equilibrium and kinetic studies. Sorption isotherms have been organized and relevant equations have been suggested. It has been defined that the kinetics of the processes in the selected concentrations under the control of the internal diffusion. Kinetic parameters have been calculated and it has been noted that heat release and entropy reduction are managed with enthalpy factor.
