摘要：
In this study, TiO2 nanoparticles composites were prepared by the micro emulsion method, above of all samples were characterized by FT-IR, XRD. Photo activities of Fe-TiO2, TiO2 were evaluated by degradation of oil-bearing wastewater. The results show that the photo activity of Fe-TiO2 was more than that of TiO2; the best presence of iron ion dopants in TiO2 was 0.04%. Used stearic acids as the surface modification agent, Fe -TiO2 were modified by situ surface modification. The results showed that the optimum conditions of stearic acid- Fe - TiO2 : Temperature (20 degrees C), the modified time (45 min), the ratio modifier dosage tomagnetitemass (4%). Then we did the initial exploration of Fe-TiO2 Powder that was modified by stearic acid.
