| Abstract: | The magnetic Fe3O4 nano-particles modified with oleic acid were prepared at 60 ℃ reaction temperature and washed with distilled water. The modified Fe3O4 nano-particles were characterized by X-ray diffraction ，infrared ray spectrum and TEM. The results showed that the Fe3O4 nano-particles modified by oleic acid had better dispersibility，stronger magnetic response and average grain size of 18 nm. |
