Preparation and Selection of New-type Visible Light Photo-catalyst Iron Nitrogen Complez

摘要：

This article explored a supported catalyst of Fe3+/Fe2+complex on cationic exchange resin as photocatalyst for the degradation of nitrilon wastewater under visible irradiation (λ>420 nm). The preparation method of catalyst and the mechanisms of affecting factors in treating nitrilon wastewater were investigated. The results were as follows: 4, 4’-bipyridyl and Fe3+/Fe2+ formate organic ion complex were loaded on cationic exchange resin with Polyallylmethacrylate, polystyrene /divinylbenzene. Per gram of resin could be loaded 4×10-4mol of organic complex. The best molar ratio of bipyridyl/Fe2+ was 2: 1 in a range of pH (3 –3.5).
