磁性Spinel型Fe-Mn氧化物/碳布纤维光催化降解磺胺废水研究

Study on Photocatalytic Degradation of Sulfanilamide Wastewater by Spinel type Magnetic Fe-Mn Oxide/Carbon fiber cloth

采用一步水热法制备了磁性Spinel型Fe-Mn氧化物/碳布纤维(FeMn2O4/CF)作为光催化剂,在可见光照射下光催化降解制药废水磺胺。考察了催化剂用量、磺胺初始浓度及初始pH值等因素,及催化剂的循环再利用性能,表明FeMn2O4/CF具有良好的催化降解性能。说明Spinel型材料在环境制药废水的处理中具有优异的发展前景。

By using one-step hydrothermal method, the paper prepares the spinel type magnetic FeMn2O4/CF, which is investigated as photocatalyst for degradation of sulfanilamide under visible light. Difference reaction conditions, such as catalyst amount, initial concentration of sulfanilamide solution, initial PH of solution are evaluated in detail. Also, the reusability of FeMn2O4/CF is studied. The results show that the Fe2Mn4O/CF has favorable photocatalytic properties and recyclability, and displays excellent development potential for environment purification of medicine wastewater.
