中文摘要：
以RuO2-IrO2-SnO2／Ti钛网电极为阳极，RuO2-IrO2／Ti钛网电极为阴极，构建了电催化氧化体系，同时以苯酚为底物、硫酸钠为电解质，考察了不同pH、极板间距、电流密度和苯酚初始浓度对苯酚去除率的影响。结果表明，在pH为6．5、极板间距为1．0cm、电流密度为50mA／cm^2、苯酚初始质量浓度为1000mg／L的最佳实验条件下，取硫酸钠质量浓度为20g／L的苯酚模拟废水250mL，120min时苯酚去除率可以达到98．4％。
英文摘要：
In this paper, the system of electro-catalytic oxidation was constructed. The anode and cathode were prepared by RuO2-IrO2-SnO2/Ti and RuO2-IrO2/Ti, respectively. The influence of pH, electrode interval, current density and phenol concentration with the substrate of phenol and supporting electrolyte of Na2 SO4 on phenol removal efficiency had been assessed. The electro-catalytic oxidation treatment in 20 g/L Na2SO4 at the pH of 6.5, electrode interval of 1.0 cm, phenol concentration of 1 000 mg/L and current density of 50 mA/cm2 , yielded the best conditions with phenol removal efficiency of 98.4% in 120 min.
