Abstract: The results of kinetic studies of regeneration for weak basic anion exchanger in NO_3~-, Cl~- and SO_4~(2-) forms are presented. A mathematical model of shell-progressive mechanism with changing bulk solution concentration and exchanger volume in ion exchange has been used to interpret the regeneration process, and the effective diffusion coefficients have been obtained.

Key words: Weak basic anion exchanger, Regeneration, Shell-progressive mechanism, Effective diffusion coefficient
