- Аннотация: A numerical study of the kinetics of ion exchange accompanied by complex formation of the ionite was made in order to explore the effect of exchange selectivity on the rate of ion interdiffusion. The ratio between the dissociation constants, K//R//A/K//R//B, for the complexes of the desorbed ions, A, and sorbed ions, B, with the fixed ions R was used as the parameter characterizing the exchange isotherm. As a result of the study, dependencies were obtained of mass transfer rate on the exchange selectivity as K//R//A/K//R//B varied between 100 and 0. 01 at different ratios between the individual diffusion coefficients D//A/D//B (10,1,0. 1). The possibility of modelling real systems was shown with particular reference to the RH-Ag** plus and RAg-H** plus exchanges in the vinylpyridinecarboxyl ionite VPC.
