Electro-Oxidation of Concentrated Ce(III) at Carbon Felt Anode in Nitric Acid Media

Original language description

Electro-oxidation of Ce (III) to Ce (IV) in parallel plate flow type electrolyzer divided with cation exchange membrane was carried out in nitric acid media at carbon felt anode under galvanostatic conditions. Carbon felt was used as an anode for its high specific surface area and high oxygen evolution overpotential. Pt coated Ti plates were used as cathode and anode current feeder. The oxidation of 1 mol/L Ce (III) solution in 2 mol/L - nitric acid was proceeding with a high current efficiency (92%) until about 80% of Ce(IV) was oxidized. Then, oxygen evolution, accompanied by terminal voltage jump, took place, lowering current efficiency. Ce(III) was oxidized up to 90% with current efficiency of 62%.
