ABSTRACT:
A process for the electronic treatment of alkali halide. Use is made of a cation exchange membrane having as its ion exchange radicals, sulfonic acid radicals. This membrane is treated with primary to tertiary monoamine or its salt or quatary ammonium salt and then heat-treated at a temperature higher than 100.degree. C. and lower than melting point of the reaction product and then subjected to drying, so as to improving the cation-selecting performance of the membrane and to increase its current efficiency.
