Abstract: The invention relates to a three-compartment electrolytic cell for production of oxidising disinfectant solutions. The intermediate compartment (300) of the cell is separated from the anodic compartment (200) by a fibrous diaphragm (321) in intimate contact with an anion-exchange membrane (320). The diaphragm (321) is formed by a network of organic polymer fibres mechanically bound to ceramic particles. The cathodic compartment (400) is separated from the intermediate compartment (300) by a cation-exchange membrane (340). Within intermediate compartment (300) a saturated solution of sodium chloride (510) is recycled. Inside tank (500) a decomposition catalyst is contained.

Abstract: An electrolytic enrichment method for heavy water includes enriching heavy water by electrolysis using an alkaline water electrolysis cell including an anode chamber that holds an anode, a cathode chamber that holds a cathode, and a diaphragm. In the method, an electrolyte prepared by adding high-concentration alkaline water to raw material water containing heavy water is circularly supplied to the anode chamber and the cathode chamber from a circulation tank; an anode-side gas-liquid separator and an anode-side water-seal device are connected to the anode chamber, and a cathode-side gas-liquid separator and a cathode-side water-seal device are connected to the cathode chamber; and electrolysis is continued while the alkali concentration in the electrolyte supplied to both electrolysis chambers is maintained at a constant concentration by circularly supplying, to the circulation tank, the electrolyte from which the gas generated from the anode-side gas-liquid separator and the cathode-side gas-liquid separator is separated.
