Title: Kinetics of ion exchange of alkaline earth metal ions on acrylamide cerium(IV) phosphate: a fibrous ion exchanger
Abstract: The kinetics of Mg(II), Ca(II), Sr(II) and Ba(II) exchange with H(I) on acrylamide cerium(IV) phosphate, a fibrous inorganic ion exchanger, was studied applying the Nernst–Planck equations. The rate of exchange is found to be particle diffusion controlled at a metal ion concentration ≥0.03 M in aqueous medium. Various useful kinetic parameters such as self-diffusion coefficient, energy and entropy of activation have been evaluated and a correlation has been made of those parameters with the ion exchange characteristics of the material.
