英文摘要: Abstract(#br)This work compares the removal of butylated hydroxyanisole (BHA), a ubiquitous antioxidant in food and pharmaceuticals, from water either by electrocoagulation (EC) with an Fe|Fe cell or H 2 O 2 -based electrochemical advanced oxidation processes like electrochemical oxidation (EO-H 2 O 2 ), electro-Fenton (EF) and photoelectro-Fenton (PEF) with an air-diffusion cathode. BHA degradation by EC was very poor, whereas the dissolved organic carbon (DOC) was more effectively abated in urban wastewater. The effect of pH, number of Fe|Fe pairs and current on the EC performance was examined. The additive was also slowly degraded by EO-H 2 O 2 with a RuO 2 -based or BDD anode in 50 mM Na 2 SO 4 solution. In the simulated matrix, BHA decay by EO-H 2 O 2 was substantially enhanced owing...
