Abstract

PURPOSE:To make it possible to perform diaphragm method electrolysis of an aq. soln. of an alkali chloride with high current efficiency by subjecting cell liquor from the cathode chamber to multistage concentration;dissolving the deposited alkali chloride in a liquid fed to the anode chamber;and removing heavy metals by filtration.
