微波辅助芬顿试剂降解联苯胺废水的研究

Synergetic Degradation of Benzidine Wastewater by Microwave/Fenton Reagent

对微波/芬顿试剂联合降解联苯胺废水进行了研究。考察了亚铁量、双氧水量、联苯胺初始浓度、微波功率、pH以及处理时间等因素对联苯胺降解效果的影响。结果表明,对于100mL,100mg/L联苯胺溶液,当加入1.0mL20mmol Fe2+,1.0mL30%H2O2,调节微波功率至460W,反应12min后,联苯胺降解率达到88.9%。通过对比试验,发现微波、芬顿试剂对联苯胺的降解起协同作用。

Degradation of benzidine wastewater by microwave/Fenton reagent was studied,and impact factors of Fe^2＋ volume,H2O2,initial benzidine concentration,pH and reaction time were investigated.Results indicated that the degradation rate of 100mg/L benzidine wastewater was 88.9% within 12min with addition of 1.0mL 20mmol Fe^2＋,1.0mL 30% H2O2,and chosen 460W of the microwave power.It was known from the contrast experiments that the benzidine was degraded by synergetic effects of microwave and Fenton reagent.
