主　　题：E-peroxone CeO_(x) Graphite felt Carbamazepine Mineralization 

摘      要：E-peroxone(EP)was one of the most attractive AOPs for removing refractory organic compounds from water,but the high energy consumption for in situ generating H_(2)O_(2) and its low reaction efficiency for activating O_(3) under acidic conditions made the obstacles for its practical *** this study,cerium oxide was loaded on the surface of graphite felt(GF)by the hydrothermal method to construct the efficient electrode(CeO_(x)/GF)for mineralizing carbamazepine(CBZ)via EP ***_(x)/GF was an efficient cathode,which led to 69.4%TOC removal in CeO_(x)/GF-EP process with current intensity of 10 mA in 60 ***,CeO_(x)/GF had the flexible application in the pH range from 5.0 to 9.0,TOC removal had no obvious decline with decrease of *** characterizations showed that CeO_(x)could enhance surface hydrophilicity and reduce the charge-transfer resistance of *** 5.4 mg/L H_(2)O_(2) generated in CeO_(x)/GF-EP process,which was 2.1 times as that in GF-EP *** greater ozone utility was also found in CeO_(x)/GF-EP *** O_(3) was activated into hydroxyl radicals,which accounted for the mineralization of *** interfacial electron transfer process was revealed,which involved the function of oxygen vacancies and Ce^(3+)/Ce^(4+)redox ***_(x)/GF had the good recycling property in fifth times use.
