Abstract

Electrodialysis (ED) is based on the electromigration of ions through cation- or anion-exchange permselective membranes that permit the passage of positive or negative ions, respectively. Ion selectivity is the results of the high electrical mobility of the counterions (ions attached to the ion-exchanger polymer) in the membrane. The counterions are easily replaced by other ions of the same charge that migrate to their respective electrode when an electrical potential is applied. Mass transfer, permselectivity, diffusion, water transport, electrotransport of large ions, energy and area requirements and resin filled cells are discussed.
