【摘要】 采用高温热氧化法制备了钛基锡锑铅氧化物电极,得到的电极具有较高的电催化活性和良好的稳定性,并以苯胺为目标有机物考察了电压、电解质的浓度、pH值和电解时间等因素对苯胺去除率和化学需氧量COD等的影响。在外加电压为8 V,电解质硫酸钠的浓度为0.15 mol/L,电解200 mg/L的苯胺模拟废水,40 min苯胺去除率可达100%,180 min时COD去除率达81.76%。更多还原

【Abstract】 The Ti/Sn,Sb,Pb oxide electrodes were prepared by thermal oxidation.The electrocatalytic activity of the electrode was increased and this electrode was highly stabilized.The results showed that the removal rates of COD and aniline were influenced by voltage,the concentration of electrolyte(Na2SO4),pH and the reaction time.With voltage of 8 V,0.15 mol/L Na2SO4,the removal rate of aniline solution(200 mg/L)was 100% when the electrolysis’s time was 40 min.When the simulated wastewater was treated for 180 min the removal rate of COD was 81.76%.更多还原
