摘要：
A shell reaction mechanism and its mathematic model were used to inquire into the kinetics of ion exchange reaction between alkaline earth metal ions and H- form of micro-crystalline SVPP.The activation energy ( Ea ), entropy of activation ( ΔS) and self-diffusion coefficient ( Do ) of alkaline earths were calculated bysolving the Nernst-Planck equations on a IBM-PC computer. The linear relations between the bare ionic radii of alkaline earths ro andEa, ΔSor lgDo have been obtained.
