抄録

The principles of electrodialysis, electrolysis and their actual conditions have been introduced mainly for applications of ion preferential permselectivity.<BR>The perfluorinated cation exchange membrane mainly uses chlor-alkali. The essentian requirements for the chlor-alkali membrane are high current efficiency and high conductivity. The chlor-alkali membranes consist of a carboxylate polymer with high current efficiency and sulfonate polymer with high conductivity to fulfill the requirements. The chlor-alkali membranes usually have a two layer structure.<BR>Ion exchange membranes with preferential permselectivity for monovalent ions are used by necessity to avoid any scale formation when producing table salt.<BR>In the case of anion exchange membranes, preferential permselectivity for monovalent anions is achieved by covering the membrane surface with a very thin layer of polyanions.<BR>On the other hand,Ion exchange membranes with preferential permselectivity between monovalent anions have also been studied.<BR>A noble kind of membrane will be developed in a variety of fields.
