METODO PER MIGLIORARE LA CARATTERISTICA DI UNA MEMBRANA A SCAMBIO DI CATIONI

摘要

PURPOSE:To improve current efficiency in electrolytic separation in an OH<->-containing aq. solution by use of homhgeneous cation exchange membranes, by subjecting the membranes to swelling treatment with a water-miscible organic solvent to reduce their OH<-> permeability.
