Abstract

Forward and reverse ion exchange kinetics of Mg(II), Ca(II), Sr(II) and Ba(II) exchange with H(I) has been studied on antimony(V) phosphate cation exchanger applying the Nernst-Planck equations. As a result, some kinetic parameters like diffusion coefficients, activation energies, and entropies of activation have been evaluated under the conditions favoring a particle diffusion-controlled mechanism. Such kinetic parameters have also been compared with the kinetic parameters of different single and double salts.
