研究了高铁酸钾和 H2 O2联用对模拟含苯废水的处理效果。考察了高铁酸钾和 H2 O2用量、pH 值、反应温度和反应时间等因素对苯去除率的影响。结果表明，在高铁酸钾与苯的物质的量比为2∶1、H2 O2与苯的质量比为8∶1、pH 值为3．5、反应温度为40℃、反应时间为30 min 时，苯去除率可达87．5％以上。通过对苯降解中间产物的红外光谱分析，推测了苯的降解机理。

The degradation of wastewater containing benzene was studied using potassium ferrate(K2 FeO4 ) combined with H2 O2 .The effects of dosage of potassium ferrate and H2 O2 ,pH value,reaction temperature and reaction time on removal rate of benzene were studied.The results showed that the optimal reaction conditions were as follows:mass ratio of potassium ferrate to benzene was 2∶1,dosage of H 2 O2 was 1.2 mL,pH value was 3.5,reaction temperature was 40 ℃,reaction time was 30 min.The removal rate of benzene reached 87.5%.The degradation mechanism was concluded by IR analysis of the degradation intermediate of benzene as well.
