摘要：本文研究了紫外光、铁离子对过氧化氢的催化分解作用.证实了紫外光和铁离子对过氧化氢的催化分解存在协同效应,并通过研究三价铁离子与紫外光的相互作用,探讨了协同效应产生的机理.UV-Fenton试剂对硝基苯、十二烷基苯磺酸钠(DBS)模拟废水的处理结果表明:将紫外光引入Fenton试剂可大大提高Fen-ton试剂的氧化性能,对生物难降解或难化学氧化的有机污染物具有良好的处理效果.
The catalysis of ultraviolet light (UV) or/and Fe (Ⅱ) to decomposition of hydrogen peroxide was studied. The existence of synergistic effect in UV-Fenton system was verified. Mechanism of synergistic effect was discussed by the study of interreaction between Fe (Ⅲ) and UV light. Besides, the experiments of simulated wastewater containing nitrobenzene or dodecyl benzene sulfonate oxidized by UV-Fenton reagent were carried out. The results indicated that the oxidation effect of Fenton reagent was greatly improved by the introduction of UV light. UV-Fenton reagent can be used to remove non-degradable or refractory organic pollutants in wastewater.
