摘要：

gamma-Al(2)O3 adsorbent modified with iron (Fe/gamma-Al2O3) was prepared by impregnation and ultrasonic wave-assisted oxidation. The optimum pH range for fluoride adsorption was 3.0-9.0, which is preferable for actual application. The maximum adsorption capacity of the Fe/gamma-Al2O3 adsorbent was 2.51 mg g(-1) and about 2 times of the plain gamma-Al2O3 (gamma-Al2O3). A column experiment was performed at an initial fluoride concentration of 30 mg l(-1), space velocity of 1.7 h(-1) and pH of 5.9, and the breakthrough time of the Fe/gamma-Al2O3 was more than 210 mm with the effluent fluoride under 10 mg l(-1) and was about 5 times of the plain one. The samples were measured by X-ray diffraction (XRD) patterns and scanning electron microscope (SEM) images.
