Inorganic ion exchange membranes

Journal of Colloid Science, 1965
Abstract A new class of ion exchange membranes has been developed for possible use in conversion of brackish water to fresh water. These membranes are based primarily on inorganic ion exchangers and have small quantities of extremely stable high temperature resistant organic polymers as binders.

Electrical capacitance of ion-exchanger membranes

Journal of Theoretical Biology, 1967
Abstract The electrical impedance of ion-exchanger membranes between identical solutions of uni-univalent electrolyte was studied. At subaudio frequencies there was a large capacitance (Farads/cm 2 ) which varied with frequency, electrolyte concentration, individual diffusion constant of membrane co- and counter-ion, and sign of membrane charge.

Liquid ion‐exchange membranes

AIChE Journal, 1973
AbstractA liquid membrane consisting of an oil layer contained between two aqueous phases was found to leak when used to transport ions selectively from one adjacent phase to another. The source of the difficulty was found to be the formation of a separate aqueous phase within the oil layer.

Modification of ion-exchange membranes

Theoretical Foundations of Chemical Engineering, 2007
Heterogeneous ion-exchange membranes with various active polymeric fibrous fillers were synthesized. The possibility of replacing polyethylene as a traditional inert polymeric carrier by poly(vinyl chloride) was analyzed.

Transport in Ion Exchange Membranes

1986
A polymeric matrix to which ionizable groups are covalently bound swells and imbibes water when immersed in an aqueous solution. Dissociation of the ionizable groups leaves charges bound to the matrix and counterions free in the absorbed water. When prepared in membrane form such polymeric matrixes are called ion exchange membranes.
