胶原纤维负载铁Fe(Ⅲ)催化剂对邻苯二甲酸二甲酯的光助催化降解特性
Catalytic degradation of dimethyl phthalate by photo-assisted Fe( Ⅲ ) immobilized collagen fiber
摘要
Abstract
Fe (Ⅲ) immobilized collagen fiber (FeCF) catalyst was prepared and its photo-assisted catalytic degradation behaviors to dimethyl phthalate (DMP) were investigated. Compared with FeCF/ H2O2/dark, FeCF/UV and H2O2/UV reaction system, FeCF/H2O2/UV is more effective for degradation of DMP. It is found that the H2O2 concentration and temperature are the main factors that greatly influence the degradation performance of DMP. Under irradiation of UV 254 nm, 100% degradation of DMP can be obtained within 30 min when the dosage of FeCF and H2O2 is 1. 0 g · L-1 and 1.0 mmol · L-1 respectively. In addition, FeCF is effective for the degradation of DMP in the wide pH range of 3.07 to 7. 96, and its photo-assisted catalytic degradation activity has no obvious decrease in 5 cycles. So, there is a potential for FeCF to treat DMP pollutant.关键词
