摘要
非均相Fenton反应能克服均相Fenton反应的诸多不足,使反应在较宽pH值范围内进行,且催化剂可反复使用。通过详细总结和评述了非均相Fenton反应处理印染废水的研究现状,包括有机载体-Fe/H2O2体系、无机载体-Fe/H2O2体系、铁氧化物/H2O2和其它金属Fe/H2O2等,指出了开发低成本、负载效果好的高催化活性的催化剂载体,进一步提高氧化剂催化部位的活性,以及提高氧化效率等是非均相Fenton反应的发展方向。
Heterogeneous Fenton reaction is superior to homogeneous Fenton reaction including wider pH range and reusable catalyst. In this paper, current studies of heterogeneous Fenton reaction in dyes＇ degradation are reviewed in detail, including organic carrier-Fe/H2O2 system, inorganic carrier-Fe/H2O2 system, ferries oxide/H2O2, other metals- Fe/H2O2 system. Developing trends of heterogeneous Fenton reaction are pointed out.
