Abstract: |
Fe3O4 was prepared by co-precipitation method with surfactants, in order to improve its stability and solubility in water. The nanometer Fe3O4@SiO2 was synthesized based on the deposition of tetraethoxysilane in H2O/CH3OH. The products were characterized by XRD, FT-IR, TEM and VSM. The investigation demonstrated that the size was 100 nm, Ms was 1.64 emu/g for Fe3O4@SiO2. Adsorption of dye on Fe3O4@SiO2 was also studied, and the maximum adsorption capacity was 6.9 ug/mg.
