摘要：

Nano-sized porous gamma-aluminas have been successfully synthesized by control precipitation method using aluminium nitrate as precursor and different precipitating agents. The synthesized materials have been characterized by SEM, FTIR, XRD and N-2 adsorption-desorption. Sample prepared by ammonium bicarbonate route possess spherical nano-sized particle with crystallite size in the range 4.7-5.7 nm, surface area 190 m(2)/g and pore volume similar to 0.467 cm(3)/g. It also exhibits excellent fluoride adsorption capacity. (C) 2008 Elsevier B.V. All rights reserved.
