胶原纤维负载铁催化剂在可见光作用下降解染料的催化特性

Preparation of Fe(Ⅲ) Immobilized Collagen Fiber and its Catalytic Behaviors in Visible Light-assisted Degradation of Dye

将Fe(III)负载到胶原纤维上制备新型非均相催化剂(FICF),研究了FICF在可见光作用下对孔雀石绿的光助催化降解特性。结果表明,当初始pH值为3.0,FICF的用量为0.50 g,H2O2用量为5.0 mmol时,FICF使500mL初始浓度为0.10 mmol/L的孔雀石绿溶液在反应进行到50 min时完全脱色,反应130 min后的矿化率为59.0%,FICF有较好的重复使用性能。

A novel heterogeneous catalyst of Fe （Ⅲ） immobilized collagen fiber （FICF） was prepared, and its visible light -assisted degradation behaviors to malachite green was investigated. It was observed that when the initial pH was 3.0, the dosage of FICF was 0. 50 g, and the offer of H2 O2 was 5.0 mmol, the deeoloration extent of 500 mL malachite green solution with concentration of 0. 10 mmol/L was 100% at 50 min, and the mineralization extent was 59. 0% at 130 min. The activity of FICF was not obviously decreased at repeated application.
