摘要

为探究Fe3O4微球的光芬顿性能

在200 ℃条件下

利用溶剂热法成功制备出具有较好分散性、平均粒径(200±0.5) nm的Fe3O4微球

并通过对其原料配比的探究进行样品优化.该合成方法所制备出的Fe3O4微球在Photo-Fenton降解亚甲基蓝方面有优秀的性能

降解率达95%甚至以上.此外

Fe3O4微球具有易回收的优点

仅利用磁场即可将其分离

且回收率超过85%甚至90%.利用回收后的Fe3O4微球探究其重复利用率

结果表明

重复利用过程中样品催化降解效率与第一次使用时几乎相同.本研究探究了该样品降解亚甲基蓝的最佳反应条件

其中当反应体系中加入15 mL过氧化氢且为酸性环境下降解效率达到最大

Abstract

In order to study photo-Fenton performance of Fe3O4 nanospheres

monodispersed Fe3O4 nanospheres with a mean diameter of 200 nm were successfully synthesized by a solvothermal method at 200 ℃. As-synthesized Fe3O4 nanospheres show excellent photo-Fenton efficiency on the degradation of methylene blue(MB)

and the degradation rate was over 95%. Besides

the catalyst was easy to recycle with only a piece of magnet

and the recovery rate can be more than 85%. Moreover

the catalyst can be regenerated with the ultrasonic treatment

and the degradation performance almost remains unchanged. In addition

the degradation efficiency varies with the amount of hydrogen peroxide applied and the pH value of the reaction system. After intensive investigation

the reaction efficiency performs best with 15 mL hydrogen peroxide added in acid atmosphere.
