THE DEPENDENCE OF ELECTRICAL CONDUCTIVITY OF ION-EXCHANGE MEMBRANES ON THE CHARGE OF COUNTER IONS
Аннотация
In this work the impedance of cation- and anion-exchange membranes has been measured
in electrolyte solutions with ions of different charges in a wide range of concentrations. It is shown
that the true value of membrane specific conductivity can be obtained only with the infinite dilution
of the equilibrium electrolyte. It has been found that the cation-exchange membrane conductivity
decreases with increasing the charge of the counter ions. The specific conductivity of anion-exchange
membranes at the infinite dilution is constant due to the fact that multiply charged anions in a neutral
medium are transferred to singly charged counter ions.
