The rate that ion B will diffuse into an ion exchange particle and replace ion A depends upon the concentration, valance state and self diffusion coefficient of the two species. The self-diffusion coefficients, DA and DB, are usually determined by measuring isotopic exchange or from a complicated cu
Thin bed experiments for the forward and reverse exchange of sodium for hydrogen and silver for potassium on DOWEX 5OW-X8 were conducted under such conditions that film diffusion controlled the exchanges. The experimental results show that the Nernst-Planck equation predicts a dependency of exchange
