Iron-Oxide–Titanium Anode for Electrolysis of

Electrophysical, electrochemical, and corrosion properties of iron-oxide-titanium anode (IOTA) in the electrolysis of chloride solutions are studied. An optimum thickness of the active mass of the IOTA coating (300 μm) is substantiated. The anode lifetime during the production of sodium hypochlorite and electrotreatment of brackish water is defined by the corrosion wear of the coating active ...
