Abstract

The electrodialysis of electrolyte solutions with differently charged cations was investigated. It was
found that the fluxes of cations through cation exchange membrane in electrodialyzer separated by
alternating cation exchange and anion exchange membranes decrease with increasing charges of cations. The
dependence of fluxes on the current density has been described by the exponential saturated curves. The
interpretation of the differences in the values of fluxes with different charges of cations was related to the
stepwise mechanism of ion transport.
