Abstract:

Fenton reaction is widely used in organic wastewater treatment. The traditional Fenton reaction can only be carried out in a acidic environment with lower pH. Variety of methods have been improved to overcome the limitations of the low pH in the classic Fenton reaction. Among of them, the use of metal catalysts in the Fenton reaction can effectively broaden the reaction pH range, reduce the formation of iron slag, and accelerate the decomposition of H2O2. This article reviews the basic principles and latest research progress of metal catalysts for Fenton reaction degradation of organic pollutants in a wide pH range.

Key words: Fenton reaction, metal catalyst, pH

摘要:

Fenton反应广泛应用于有机废水处理,但传统的Fenton反应只能在pH较低的酸性环境下进行。为克服经典Fenton反应低pH的局限性,进行了多种方式改良。其中,在Fenton反应中采用金属催化剂能有效拓宽反应pH范围,减少铁渣生成,加快H2O2分解。综述了金属催化剂在宽泛pH范围进行Fenton反应降解有机污染物的基本原理和最新研究进展。
