Abstract
Method and apparatus for electrolytic generation of permanganate. The invention includes a manganese dioxide adherent cathode surface which eliminates undesirable reduction reactions at the cathode during electrolysis thereby increasing permanganate generation efficiency.
Claims16
A process for permanganate generation by electrolytic oxidization of one or more manganese compounds in a solution, comprising the steps of:
- (a) contacting an anode and a cathode with the solution, the cathode having a surface deposit being adherent to manganese dioxide during electrolysis of the solution;
- and
- (b) subjecting the solution to electrolysis.
A process for permanganate generation by electrolytic oxidation, comprising steps of:
- (a) contacting an anode and cathode with a solution comprising one or more manganese compounds, at least portions of the surface of the cathode being comprised of nickel;
- and
- (b) subjecting the solution to electrolysis.
A system for permanganate generation, comprising:
- (a) a volume of an aqueous solution comprising one or more manganese compounds;
- and
- (b) an anode and cathode contacting the solution, at least portions of the surface of the cathode comprising a compound adherent to manganese dioxide during electrolysis of the solution.
