摘要：

A thermodynamic approach to describing ion exchange and superequivalent absorption that occur simultaneously is proposed, based on the stoichiometry of both processes. This approach allows us to calculate the activity coefficients of components of the sorbent phase and the thermodynamic constants of ion exchange and superequivalent absorption.
