摘　　要：BDD电极的析氧电位最高达2.8 V,表现出极好的电化学性能。D iachem(、Si/BDD、Nb/BDD、Ti/BDD电极及表面改性后的BDD电极可在电极表面产生具有强氧化性的羟基自由基,对酚类、染料、农药和表面活性剂等有机废水的降解能力较强。BDD电极可降解多种有机物,电流效率>90%,可使有机物完全矿化。BDD电极在有机废水处理中应用前景良好。Boron-doped Diamond （BDD） electrode exhibits an electrochemical potential of up to 2.8 V for oxygen generation. This kind of electrode shows very excellent electrochemical performance. The hydroxyl radicals generated from Diachem, Si/BDD, Nb/BDD, Ti/BDD and surface modified BDD electrodes have strong capacity in degradation of hazardous or persistent pollutants in different organic wastewaters such as phenolic compounds, dyes, pesticides and surfactants etc. BDD electrode can degrade various organic pollutants. Current efficiencies of more than 90% and pollutants being completely mineralized have been demonstrated. BDD electrode will be applied in organic wastewater treatment widely.
