The selectivity coefficient K21 of an ion-exchange process is in general a function of the ionic composition of the material. As a result, the value of K21 will change continuously during a com­plete conversion of the ion-exchanger. Equations for the kinetics of such a conversion with variable K21 are given for a film diffusion controlled ion-exchange reaction.
