以热氧化法制备的ＳｎＯ２／Ｔｉ 电极作为阳极用于含苯酚酸性溶液的恒电流电解，测定了苯酚浓度、溶液中化学需氧量（ＣＯＤ） 以及瞬时电流效率等随电解时间的变化．结果表明，用ＳｎＯ２／Ｔｉ 电极代替铂作为阳极可使相同氧化电量下的ＣＯＤ 明显下降，而平均电流效率提高了３倍．讨论了两种电极上苯酚氧化的反应机理
A SnO 2/Ti electrode prepared by thermal oxidation was used as the anode for galvanostatic electrolysis in acidic solution containing phenol, the time_dependances of phenol concentration,chemical oxygen demand in solution(COD)and instantaneous current efficiency were determined during electrolysis.The results show that with the SnO 2/Ti anode instead of Pt,the COD significantly decreases at the same charge passage, and average current efficiency of oxidation increases by three times The mechanism for phenol oxidation at two electrodes was discussed.
