Fenton试剂对硫化物的处理效果研究

Study on removal effect on sulphide by Fenton reagent

应用芬顿试剂对硫化物去除效果及影响因素进行研究.结果表明,pH值对硫化物的去除率的影响很大,反应时间起始质量浓度和温度对硫化物的去除率的影响较小.当H2O2和Fe2+的摩尔比为4,pH=4.0,硫化物质量浓度为12mg/L时,硫化物去除率最高可达到99%以上,说明Fenton试剂可将硫化物基本完全去除.

In this paper, the removal effect of sulphide by Fenton reagent is dicussed. The results showed that pH value is a key factor and the react time, origination concentration and temperature have noobvious effect on sulphide removal. When the mol ratio of H_2O_2/Fe^(2+) is 4, pH=4.0,S^(2-)=12 mg/L,more than 99% maximal removal effect of sulphide can be attained. So it indicated that the sulphide can be almost fully removed by Fenton reagent.
