Abstract

The technique of modification of commercial anion exchange membranes with bifunctional
electrolytes, during which the secondary and tertiary surficial amino groups transform into quaternary
ammonium bases, was developed. It was shown that such modification of homogeneous AMX membranes
can promote the limiting and overlimiting transport of salt ions. The reasons for this are suppression of H+,
OH– ions generation and more intensive development of electroconvection.
