摘要
对UV/Fe0协同降解对硝基苯胺废水进行了研究,分别考察了铁粉量、pH、对硝基苯胺初始浓度以及反应时间等影响因素对废水降解效果的影响。结果表明,对于50 mg/L对硝基苯胺废水溶液,pH=3时,当加入30 mg/L的铁粉量,反应180 min后,对硝基苯胺降解率达到了93%。通过对比实验,发现UV/Fe0体系较UV/Fe2+体系对对硝基苯胺具有更好的降解效果。
The degradation ofp-nitroaniline （p-NA） wastewater by UV/Fe0 system has been studied. The effects of Fe^（iron powder） dosage ,pH,initial p-NA concentration and reaction time are investigated. The results show that the degradation rate of 50 mg/L p-NA wastewater reaches 93%, when its reaction time is 180 min, Fe0 dosage is 30 mg/L and pH is 3.0. It is found from the contrast experiments that the degradation efficiency ofp-NA has better per- formance in UV/Fe0 system than that of in UV/Fe2＋system.
