Mediated electrochemical oxidation (MEO) is an ex situ treatment technology that uses electricity, acid, and a metal catalyst to destroy organic wastes at low temperatures and pressures. The proprietary CerOx Corporation MEO configuration uses cerium metal as a catalyst to oxidize organic waste into carbon dioxide and water. The process occurs in an acidic solution, typically nitric acid. The first step involves the generation of an oxidant at the anode, followed by the reduction of water or another chemical species at the cathode. This technology serves as a nonthermal alternative to incineration.

It has been proposed that mediated electrochemical oxidation may be used for the ambient temperature destruction of hazardous waste. Using Co(III)- -mediated electrochemical oxidation in sulfuric acid, l,3-dichloro-2-propanol and 2-chloro-l-propanol were oxidized to carbon dioxide259. A series of studies is being conducted on the use of the anodic oxidation of barium peroxide to produce an intermediate that leads to destruction of halogenated organic compounds. 

Mediated electrochemical oxidation (MEO) is a special case of indirect oxidation whereby metal ions with high oxidation potential (e.g., Ag(II), Ce(IV), and Co(III)) are electrochemically generated in a closed cycle [14].
