dc.description.abstract | The removal of benzophenone-3 (BP-3), a ubiquitous pollutant in municipal wastewater treatment fa-cilities, was optimal by means of a sequential electrocoagulation (EC)/UVA photoelectro-Fenton (PEF)treatment. Overall mineralization was attained upon combination of EC (Fe/Fe cell, 15 mA cm 2, 20 min)with PEF (boron-doped diamond/air-diffusion cell, 33.3 mA cm 2, 720 min), being superior to EC/electro-Fenton (EF) and requiring shorter time than single PEF. In EC, an Al/Al cell yielded the largest removal ofBP-3 in a simulated matrix at pH 11.0 due to precipitation of its neutral form caused by a substantial pHdrop, with optimum current density of 15 mA cm 2. EC of BP-3-loaded urban wastewater at natural pHwas quite effective also with a Fe/Fe cell, being preferred since it provided the required metal catalyst forsubsequent treatment. Among the electrochemical advanced oxidation processes tested, PEF was su-perior to electrochemical oxidation with electrogenerated H2O2(EO-H2O2) and EF, especially when usingthe boron-doped diamond instead of a RuO2-based anode, due to the oxidation of generated activechlorine and hydroxyl radicals, along with the photolytic action of UVA irradiation. GC-MS revealed theformation of 14 cyclic products in PEF treatment, two of them being also formed during EC. | - |
