摘要
采用超声辅助电催化氧化法协同降解苯酚,考察电解质种类及浓度因素等对苯酚降解率的影响,利用高效液相色谱法分析苯酚的降解率.实验结果表明:NaCl和Na2SO4均可在一定程度上促进苯酚的降解,但NaCl(30.40%)作电解质时对苯酚的降解效果要明显优于Na2SO4(17.17%),且当NaCl电解液浓度在0.12~0.16mg/mL范围内时苯酚的降解效率最佳;超声波和电催化氧化两种降解技术同时进行具有很好的协同效应,降解率最高可达96.43%,实现真正意义上的1+12.
Phenol was degraded using the method of ultrasound-assisted electrocatalytic oxidation.Influence of kind and concentration of electrolyte on phenol degradation rate were investigated,and the degradation rate of phenol was measured by high performance liquid chromatography(HPLC).The result shows that both NaCl and Na2SO4 can promote the degradation of phenol,but the degradation rate of phenol is obviously better when NaCl(30.40%)is as the electrolyte than that of Na2SO4(17.17%),and the degradation efficiency of phenol is the best when the concentration of NaCl electrolyte is between 0.12mg/mL and 0.16mg/mL.It shows good synergistic effect when the two degradation technologies of ultrasonic and electrocatalytic oxidation proceed at the same time,the highest degradation rate is up to 96.43%,and 1+12will be the real true.
