Research progress of heterogeneous Fenton catalyst for organic wastewater treatment

Abstract

The catalytic degradation of organic wastewater by heterogeneous Fenton has attracted much attention in recent years. Compared with homogeneous Fenton, heterogeneous Fenton reaction has the advantages of wide pH range, low dissolved iron content after reaction, easy magnetic separation and good reusability. This paper mainly introduces the research progress of heterogeneous supported Fenton catalyst in the treatment of organic wastewater in recent years. In this paper, the degradation performance and recyclability of organic wastewater by catalysts are discussed, and the development direction of catalysts in the future is prospected.
