Recent Developments on Ion-exchange Membrane Processes ; Progress Report

Abstract

Recent progresses on ion-exchange membrane technology are critically reviewed. This includes principally the papers published in 1982-1984. Especially, the following interesting topics are explained and discussed; new ion-exchange membranes, perfluorocarbon ion-exchange membrane such as Nafion membrane, instabilities accompanied by concentration polarization in electrodialysis including the mechanistic studies on water dissociation in salt-depleted layer at membrane surface, new functional membranes such as ion-gate membrane, and recent developments on ion-exchange electrodialysis and its applications.
