Monovalent Selective Cation-exchange Membranes Prepared by Plasma-induced Graft Polymerization

抄録

In electrodialysis （ED） using ion-exchange membranes （IEMs）, the occurrence of scale precipitation makes continuous operation of the equipment difficult. As a solution to this problem, we developed a monovalent selective cation-exchange membrane （MS-CEM） prepared via plasma-induced graft polymerization by grafting monomers with oppositely charged groups onto a commercial （ungrafted） CEM. As a result, the permselectivity of the prepared MS-CEM was approximately 4.3 times higher than that of the ungrafted CEM.
