Electrochemical studies on polystyrene based membrane of zirconium(IV) antimonoarsenate

Electrochemical studies have been carried out on heterogeneous ion-exchange membranes of zirconium(IV) antimonoarsenate using polystyrene as a binder. Electrical characteristics like transport number, permselectivity and fixed charge density of the exchanger membrane and halide salts of some alkali and alkaline earth metals as electrolytes have been determined. The membrane potential data conforms to the Kobatake theoretical treatment of irreversible processes. The effect of electrolyte concentration on transport numbers and permselectivity has also been studied. Results indicate that the. membrane is permselective for counterions and possesses weak electrical character.
