Abstract

a. L'invention a pour objet une cellule à cathode de mercure pour l'électrolyse de solutions aqueuses de chlorure de métal alcalin, qui est conçue pour réduire la teneur en acide hypochloreux des solutions aqueuses extraites de la cellule. b. La cellule comprend, outre les anodes et la cathode de mercure, une surface catalytique en un matériau qui catalyse la décomposition de l'ion hypochloreux. c. L'invention s'applique aux cellules à cathode horizontale ou oblique de mercure, pour l'électrolyse des saumures de chlorure de sodium.at. The invention relates to a mercury cathode cell for the electrolysis of aqueous solutions of alkali metal chloride, which is designed to reduce the content of hypochlorous acid in aqueous solutions extracted from the cell. b. The cell comprises, in addition to the anodes and the mercury cathode, a catalytic surface made of a material which catalyzes the decomposition of the hypochlorous ion. vs. The invention applies to cells with a horizontal or oblique mercury cathode, for the electrolysis of sodium chloride brines.
