Abstract

The equilibrium sorption of Cu 2+ , Zn 2+ , Cd 2+ and Pb 2+ -ions by polyampholytes Daion CR-11(with iminodiacetic group, Na + ) and Duolite C-467 (with amino-fosfon group, Na + ), depending on the degree of neutralization of the ionogenic groups, concentrations of solutions and acidity is investigated. Equilibrium and kinetic parameters of sorption processes are defined, thermodynamic quantities are calculated.
