| Abstract: | The Fe3O4 nano-particles and oil up on the Fe3O4 fluid are prepared by a chemical co-precipitation method and hydrothermal method.The optimum reaction conditions are determined through experiments.The crystal structure of Fe3O4 particles is analyzed via X-ray diffraction(XRD);the microstructure of magnetic fluid sample is observed via transmission electron microscope(TEM);the effects of nano-particles on the degradation of levofloxacin solution imitating wastewater is investigated by high performance liquid chromatography(HPLC).The results show that the product is inverse spinel structure of the cubic crystal system-type compounds of AB2O4.The average particle size is less than 15 nm;magnetic fluid is regular spherical shape basically,particles uniformly and without agglomeration.Magnetic fluid samples are of good mobility and superparamagneticity;nano-size Fe3O4 can degrada levofloxacin to a certain extent. |
