Studies on anion exchange membranes having permselectivity for specific anions in electrodialysis — effect of hydrophilicity of anion exchange membranes on permselectivity of anions

Journal of Membrane Science, 2000
Abstract Recent studies on anion exchange membranes and electrodialysis methods to permeate specific anions through the membranes are reviewed. The studies are classified: (1) to increase cross-linkage of the anion exchange membranes, (2) to form tight surface layers on the anion exchange membranes, (3) to decrease hydrophilicity of the anion ...

Contamination of an anion-exchange membrane by glutathione

Bioseparation, 2000
Electrodialysis, which can separate electrolytes under mild conditions by using ion-exchange membranes, is a strong candidate for separation of GSH from yeast extracts, because GSH is unstable and easily oxidized forming a disulfide bond especially under alkali conditions. In this paper, sorption behavior of GSH on an anion-exchange membrane, in the pH
