Method for manufacturing anode for fluorine gas electrolytics synthesis

Abstract

Provided is a method for manufacturing an anode where the anode effect is not likely to occur even when an electrolytic solution containing hydrogen fluoride and a metal fluoride is electrolyzed and used for electrolytically synthesizing fluorine gas. The method for manufacturing an anode for fluorine gas electrolytic synthesis includes an anodic treatment step. The anodic treatment step is a step of immersing not only an anode (21) that is an anode substrate including a carbon material but also a cathode (22) in a mixed liquid (10) for manufacturing an anode containing hydrogen fluoride, a metal fluoride, and potassium hexafluoronickelate (IV) and causing a current to flow between the anode (21) and the cathode (22) to perform an anodic treatment of the anode substrate such that nickel fluoride is attached to a surface of the anode substrate.
