Membrane potential of bipolar membranes

Journal of Electroanalytical Chemistry, 1996
Abstract The membrane potential of a bipolar membrane composed of a cation-exchange layer in series with an anion-exchange layer is analyzed theoretically and experimentally. The theoretical approach is based on an extension of the Nernst-Planck equations of monopolar charged membranes to the case of the two ion-exchange layers in series and the ...

Preparation of bipolar membranes. II

Journal of Applied Polymer Science, 2001
AbstractThe bipolar multilayer membrane was prepared by a new technique. The interfacial layer and cation layer were formed by only one step. The anion and cation layers were made from the same material from which chloromethylated polysulfone was used as a basic material.

Effect of Number of Bipolar Membranes and Temperature on the Performance of Bipolar Membrane Electroacidification

Journal of Agricultural and Food Chemistry, 1997
The purpose of this study was to evaluate the effects of stacking bipolar membranes (1−4 BPMs) on the energy and electroacidification parameters, as well as the temperature (10, 20, and 35 °C) on the efficiency of bipolar membrane electroacidification (BMEA) of soybean protein for the production of isolate. BMEA is based on the production of protons by

Studies on bipolar membranes

Reactive and Functional Polymers, 1996
Abstract Bipolar membranes are composed of two distinct layers which are selective to ions of opposite charges. Because of this unique characteristics, bipolar membranes are able to electrically separate water into hydrogen and hydroxyl ions. These membranes in conjunction with conventional cation- and anion-exchange membranes in a cell stack, have ...

Development of bipolar membranes

Desalination, 1988
Abstract The large-scale industrial use of bipolar membrane for the production of acids and bases from the corresponding salts is limited by the properties of the commercially available bipolar membranes. Today's membranes are unsatisfactory in terms of their selectivity and chemical stability at high pH values.
