摘要(Abstract):
[目的]研究Fenton氧化降解活性艳红X-3B的条件及历程。[方法]利用Fenton氧化工艺,分析3种不同初始浓度的活性艳红X-3B废水的降解条件,同时利用GC-MS对其降解产物及历程进行研究。[结果]当H2O2∶Fe2+(摩尔比)=3.1时,COD去除效果最好,随着Fe2+投加量的增加,废水会变成铁红色,同时沉淀物增加;对于COD分别为200、400和800 mg/L的废水,H2O2投加量分别为0.5、1.0、3.5 ml,废水的初始pH为4~5时,COD的去除率最高。Fenton氧化反应的速度非常快,大部分的降解都发生在初始的5 min之内。[结论]Fenton氧化技术是一种高效降解难降解染料的实用技术。
