Abstract
Separation of calcium and sodium chloride solutions in electromembrane systems (EMS) based on homogeneous sulfonate-containing ''Kaspion'' m embranes are studied. It is demonstrated that the degree of separation of the mixture of monovalent (Na+) and bivalent (Ca2+) ions in such s ystems increases with the increasing density of the polarizing current reaching anomalously high (compared with the known values for EMS, in cluding sulfocationic surface-modified membranes) values.
