| Abstract: | Nano-A12O3 was successfully prepared by sol-gel method.The nano-A12O3 prepared under different temperature was characterized by transmission electron microscopy（TEM）,X-ray diffraction（XRD）,Brunauer Em-Mett Teller（BET）.The adsorption of Cu2＋ and Pb2＋ on the alumina powder was investigated by solid-phase extraction and ICP-MS with different sizes and different crystal form.The results indicated that the extraction efficiency of nanometer Al2O3 decreases with the increase of size,γ-Al2O3 has the obvious adsorption to Cu2＋ and Pb2＋ than α-Al2O3.The detection limit for Cu2 ＋ and Pb2 ＋ was 10 ng.L-1 and1.0 ng.L-1 respectively. |
