| 英文摘要 | 伪-Fe203 hollow micospheres have been successfully synthesized by solvothermal method at 200 掳C. The synthesized products are characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and the nitrogen adsorption-desorption isotherm technique. The 伪-Fe 203 hollow microspheres have an average diameter of 2-3 m, the shell consists of numerous aligned nanorods with length of about 200-400 nm. The effects of solvent and reaction time have been studied. The Ostwald ripening mechanism is proposed to account for the formation of 伪-Fe 203 hollow microspheres. Because of the porous hollow microstructure and large specific surface area, the microspheres were found to be effective sorbents for the removal of Cr(Vl) ions from wastewater.
