Abstract
In the future, mediated electrochemical oxidation (MEO) may be used for the ambient temperature destruction of hazardous waste and for the conversion of mixed waste to low‐level radioactive waste. We have studied the Co(III)‐mediated electrochemical oxidation of ethylene glycol, 1,3‐dichloro‐2‐propanol, 2‐monochloro‐1‐propanol, and isopropanol in sulfuric acid. The electrochemical reactor had a rotating cylinder anode that was operated well below the limiting current for Co(III) generation. Rates of generation were measured and used to calculate both destruction and current efficiencies for the process. We found that electrode separators can be eliminated in MEO processes based upon Co(III) and sulfuric acid. Electrodes must be separated by ion exchange membranes in classical Ag(II)‐based processes.
