摘要
通过水热法制备了花状MgFe_2O_4/Bi_2WO_6磁性复合光催化剂,其中掺杂比例为10%的MgFe_2O_4/Bi_2WO_6的光降解效果最好,当丁基黄药的初始浓度为50 mg/L,光催化剂投加量为0.5 g/L时,经过120 min光照,丁基黄药的降解率能达到96%。这个实验是面向理工类本科学生的一个开放性实验。要求学生独立查阅文献资料、设计实验方案、操作、数据分析、撰写报告,最终培养综合创新能力。
The flower-like morphology MgFe2Oi/Bi2 WO6 magnetic composite photocatalyst was successfully prepared by hydrothermal method. The photocatalytic activ让y of 10% MgFe2Oi /Bi2 WOfi is the best. When the initial concentration of butyl xanthate was 50mg/L and the dosage was 0.5g the degradation rate of butyl xanthate can reach 96%. This opening experiment was designed for the science and engineering undergraduate. The students need to do literature searching, experimental s*cheme operation, data analysis and report writing independently. The purpose is to promote their mixed ability and innovation ability.
