Abstract
Using the algebraic formula derived earlier to determine the electroosmotic permeability of an ion-exchange membrane at a given constant current density, experimental results obtained by the authors for an extrusion perfluorinated membrane and aqueous solutions of the 1 : 1 electrolytes HCl, NaCl, KCl, LiCl, and CsCl have been analyzed. A cell model has been successfully tested using experimental data on the electrical conductivity and electroosmotic permeability of the MF-4SC cation-exchange membrane at given current density and concentration of these electrolytes. A good agreement between the theoretical and experimental data has been obtained, and the physicochemical parameters of the cell model have been determined.
