Abstract
An electrolytic cell and a method of electrochemical oxidation of manganese (II) ions to manganese(III) ions in the electrolytic cell are described. The electrolytic cell comprises (1) an electrolyte solution of manganese(II) ions in a solution of 9 to 15 molar sulfuric acid; (2) a cathode immersed in the electrolyte solution; and (3) an anode immersed in the electrolyte solution and spaced apart from the cathode. Various anode materials are described including vitreous carbon, reticulated vitreous carbon, and woven carbon fibers.
Claims21
A method of electrochemical oxidation of manganese (II) ions to manganese (III) ions comprising the steps of:
- providing an electrolyte comprising a solution of manganese (II) ions in an acid solution in an electrolytic cell wherein the electrolytic cell comprises an anode and a cathode, and wherein the anode comprises a material selected from the group consisting of vitreous carbon, reticulated vitreous carbon and woven carbon fiber;
- applying a current between the anode and the cathode;
- and
- oxidizing the electrolyte to form manganese(III) ions, wherein the manganese(III) ions form a metastable complex.
