Transport–Structural Parameters of Domestic and Foreign Anion-Exchange Membranes

The concentration dependences of the electroconductivity, diffusion penetrability, and transport numbers for water in anion-exchange membranes of domestic and foreign production are studied in identical conditions in NaCl solutions with the aid of a complex of standardized methods of conditioning the samples and measuring their properties. The dependences of the electroconductivity and the diffusion flux of the salt are used to calculate transport–structural parameters, which characterize conducting properties of membranes in the framework of a heterogeneous model. Electrotransport properties of anion-exchange membranes are compared and factors that affect them are discussed.
