Preparation And Selection Of New-Type Visible Light Photo-Catalyst Iron Nitrogen Complex

This article explored a supported catalyst of Fe(3+)/Fe(2+) complex on cationic exchange resin as photocatalyst for the degradation of nitrilon wastewater under visible irradiation (lambda>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 Fe(3+)/Fe(2+) formate organic ion complex were loaded on cationic exchange resin with Polyallylmethacrylate, polystyrene/divinylbenzene. Per gram of resin could be loaded 4 x 10(-4)mol of organic complex. The best molar ratio of bipyridyl / Fe(2+) was 2: 1 in a range of pH (3-3.5).
