✦ Synopsis

A model for multispecies ion-exchange kinetics based on the Nernst-Planck equation is suggested. It is analyzed in comparison with the "locally-determinate" model described by Hwang and Helfferich [l]. The model makes possible simple computation. The conditions for the occurrence of unusual kinetic curves with a maximum are clarified. The proposed model is developed for different types of kinetic problems and verified by the experimental investigation of a kinetics in ternary systems.

Four cases of ion-exchange kinetics are pointed out in which premises of a mathematical model are incompatible with facets of physical reality. The cases are (1) calculation of nonlinear gradients in an unstirred Nernst "'film'" (2) shell-core models in the absence of a mechanism that can produce sh
