| 摘 要： | 采用后接枝法将氨丙基三乙氧基硅烷接枝到二氧化硅网络中，合成了氨丙基功能化的MCM-41介孔硅。FTIR结果显示，氨基被共价键键合到了介孔硅基体上。实验结果表明，所制备的功能化材料可以选择性吸附水溶液中的pb2＋，最大吸附量为193mg·g1。

| Abstract: | 3-Aminopropyltriethoxysilane was introduced into the network of silica through post-grafting and amino-functionalized MCM-41 mesoporous silica was obtained. FTIR characterization revealed that amino had been covalently bonded onto the surface of mesoporous silica. Experimental results showed that the as-synthe- sized functionalized material could selectively adsorb Pb2 ＋ from aqueous solution. The maximal adsorption capac- ity of Pb2 ＋ for amino-functionalized mesopomus silica was 193mg@ g- 1. |
