An experimental study has been made of the neutralization of a strong-acid ion exchanger by strong-base solutions in the intraparticle diffusion controlled region. Data obtained in a well-stirred batch reactor were consistent with the theory of Helfferich and yielded reasonable values for intraparticle diffusivities. However, the results have also shown that the model fails to account properly for the effects of different co-ions.
