It is found that the DBL near an ionexchange membrane is formed quasi-instantly under natural convection and follows the variation in solution concentration drop through the DBL (Dc): d ~ (Dc)–0.2. The fact that the value of power differs from the value predicted by Levich (–0.25) is explained by th

It is found that under certain conditions (a dilute solution, a relatively small inter-membrane distance, and a significant forced convection), the contribution of the gravitational convection in the ion transfer is negligible. Considerable electroconvective mixing of the depleted solution starts at

Two 2D models of non-stationary and non-isothermal transfer of a strong binary electrolyte in a rectangular electrodialysis desalination cell formed by anion- and cation-exchange membranes are developed. Both gravitational and forced convection occurring in underlimiting current mode are taken into

Concentration dependencies of the membrane electric conductivity under alternating current and fluxes of anions through anion-exchange membranes (AEMs) under direct current were measured in 0.002–1.0 M sodium salt solutions of carbonic and phosphoric acids. Several commercial AEMs were studied: AFN,
