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.
