摘要 采用共沉淀法成功制备出MnFe_(2)O_(4)磁性纳米球,并采用采用X射线衍射(XRD)、N_(2)吸附-脱附、振动样品磁强计(VSM)和透射电镜(TEM)对其理化性质进行了表征。类Fenton氧化降解氧氟沙星的结果表明,MnFe_(2)O_(4)磁性纳米球比Fe_(3)O_(4)的催化活性高,反应180 min,氧氟沙星的去除率可以达到78.5%,TOC的去除率达到54.3%。 Magnetic MnFe_(2)O_(4)nanospheres were successfully prepared by the solvothermal method.The physical and chemical properties of the prepared MnFe_(2)O_(4)nanospheres were characterized by X-ray diffraction(XRD),N_(2) adsorption-desorption,vibrating sample magnetometer(VSM)and transmission electron microscopy(TEM).The results showed that MnFe_(2)O_(4)nanospheres exhibited higher catalytic activity in the degradation of ofloxacin than that of Fe_(3)O_(4).After the reaction of 180 min,the removal rate of ofloxacin and TOC were 87.6%and 47.5%,respectively.
