METHOD TO DETERMINE THE SUITABILITY OF DIAPHRAGM FOR USE IN ELECTROLYTIC CELL

摘要

An electrical method to determine the suitability of a diaphragm for use in an electrolytic cell. The method comprises inserting the diaphragm between a primary anode and a primary cathode immersed in an electrolyte and then impressing a known direct current electromotive force between the electrodes. The change in electrical properties across the electrolyte resulting from insertion of the diaphragm is determined. Such change is indicative of the suitability of the diaphragm for use in an electrolytic cell and can be a measure of diaphragm uniformity.
