Concurrent electrical mass transfer of the sodium and barium ions through perfluorinated ion-exchange membranes

The radioactive tracer method is used to study mass transfer and electrical mass transfer of sodium and barium ions from their individual solutions and from their mixture through perfluorinated ion-exchange membranes with and without a surface-modified layer. The mutual influence of ions in the course of their simultaneous transfer through a membrane is determined by the membrane's total moisture content, which is defined by the external electrolyte composition and the hydration degree of ions being transferred.
