A differential equation describing the kinetics of film diffusion controlled ion exchange processes is derived on the basis of the theory of irreversible thermodynamics. This equation is solved subsequently with the boundary conditions of infinite solution volume and applied to some experimental results involving differential ion exchange reactions. In case of the boundary conditions of a finite solution volume, the kinetics of dissolution of a sparingly soluble salt by an ion exchanger is considered.
