Abstract :Sorption regularities of Zn 2+ and Pb 2+ ions from water solutions by ion exchangers of Diaion CR 11, Amberlite IRC 748 with iminodiacetic acid functional group and Dowex M 4195 with bis-picolilamine functional group are investigated, sorption isotherms are plotted, isotherms are analyzed on the basis of known models, thermodynamic parameters are calculated on the basis of kinetic data, thermodynamic factor controlling processes is determined.  
Keywords : ion exchangers, Zn2 and Pb2 ions, sorption isotherms, Langmuir and Freundlich models, kinetic and thermodynamic parameters
