An analytic solution of the Nernst‐Planck equations is derived which applies to a selective resin when film diffusion controls. The selectivity has a marked effect on the rate of exchange for a wide range of diffusivities. The unit‐selectivity solution of Schlögl and Helfferich is included as a special case of the more general solution.
