Fenton法中拓宽pH范围的方法

Ways to widen pH range in Fenton process

传统的Fenton法处理废水时,须调节处理前后废水溶液的pH,制约Fenton技术的广泛应用。本文分析了拓宽Fenton法pH范围的可能途径,综述了关于络合剂、类铁金属的离子及固体催化剂等方法的研究成果,指出了值得进一步深入研究的问题。

The traditional Fenton oxidation process always needs solution with pH value under 3 in treatment of wastewater,this limits its application. The ways to widen pH range in Fenton process are discussed in this paper, with the advances of several methods reviewed such as using chelates, iron-like ions or solid catalysts. Some problems which ought to be deeper in research are also pointed out.
