Abstract

Use of autoradiography and scanning electron microscopy, coupled with potentiometric and radionalytical investigation techniques, allows to confirm experimentally that the rate of Cl−→SO 2−4 conversion of different anion resins at 0.006N solution concentration is not controlled) by ion interdiffusion and that sulfate penetration into the resin bead occurs according to a progressive conversion mechanism.
