Abstract: A novel lead dioxide anode modified by fluorine and characterized by X-ray diffraction (XRD) and SEM, was applied to the organic degradation by using phenolic compounds as model pollutants. It was found that this anode showed good resistance to corrosion, perfect electrocatalytic activity and stability, indicating potential for future environmental application. Further, the degradation of organics was confirmed to be mainly of the hydroxyl radical mechanism by using isopropanol as radical scavenger, hence, such an oxidation process is essentially an advanced electrochemical oxidation process (AEOPs).
