Preparation and Characterization of Stearic Acid- Modified Iron-doped TiO2 Nanoparticles
In this study, TiO2 nanoparticles composites were prepared by the micro emulsion method, and these samples were characterized by FT-IR, XRD. Photo activities of Fe-TiO2, moreover the TiO2 were evaluated by degradation of oil-bearing wastewater. The results showed 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％. When stearic acid was applied for the surface modification agent, the Fe TiO2 was modified by in situ surface modification. The optimum conditions of stearic acid- Fe - TiO2 was: temperature (20℃), the modified time (45 min), the ratio modifier dosage tomagnetitemass (4％). So the TiO2 nanoparticles composite was a kind of effective materials for oil-bearing wastewater.
