Electrochemical oxidation processes have been used for treating various wastewater since it produces highly active hydroxyl radicals (•OH) that are promising in the removal of anions, toxic metals, pharmaceuticals, chromium, arsenic, organic pollutants, and bio-refractory wastewater.
Various electrode materials include BDD, PbO2, Pt, Ti/IrO2, glassy carbon, SnO2-Sb and graphite have been investigated for the electrochemical oxidation of organic pollutants. Some anodes favor the selective oxidation or conversion of the organics
