Electrochemical advanced oxidation process (EAOP) is a new type of electrochemical oxidation. The electrochemical oxidation process involves the application of an external source of energy into an electrochemical cell that contains one or more pairs of electrodes. At the cathode, a reduction reaction occurs, and the oxidation reaction takes place at the anode.
EAOP can eliminate contaminants at the interface of the anode/aqueous solution (direct oxidation), and via anodically generated intermediates e.g. reactive oxygen species like hydroxyl radicals (HO•) and active chlorine species (indirect oxidation). Hydroxyl radicals are highly reactive oxidants that can react with nearly.
