Abstract
Equilibrium (the exchange capacity and moisture content) and transport (the ion transport numbers and the electrical conductance) properties of perflu orinated cation-exchange membranes containing carboxyl groups were studied as a function of pH and concentration of KCl solutions (10(-4)-1 M). Dissoc iation constants of carboxyl groups, adsorption potentials of K+ ions, tran sport numbers and mobilities of counterions in the membranes, concentration s of fixed ions, co- and counterions, as well as the Donnan potentials were calculated.
