Title:
TREATMENT OF CATHODE IN ELECTROLYTIC CELL
Document Type and Number:
Japanese Patent JPS6059090
Kind Code:
A
Abstract:
A method of treating the surface of a cathode in order to remove therefrom deposited iron, the cathode comprising a metallic substrate at least part of the surface of which has been activated in order to reduce the hydrogen overvoltage at the cathode when the cathode is used in the electrolysis of water or aqueous solutions, and the method comprising contacting the surface with a liquid medium which reacts with and solubilises the deposited iron.Removal of deposited iron results in a decrease in the hydrogen overvoltage of the cathode. The liquid medium may be an aqueous acidic solution and the cathode may be contacted with the liquid medium in situ in the electrolytic cell
