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.
