Abstract
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, AMX, ACS and ACM produced by Tokuyama Soda (Japan), Anion 204SZRA by Ionics (USA), ADP by Morgan (France) and MA-40, MA-41 by Schekino (Russia). Transport properties of these membranes are interpreted as functions of the internal solution pH. The mechanism of (hydro)carbonates transfer through AEMs is discussed.
