| 摘 要： | 以介孔二氧化硅为载体,3-氨基丙基三乙氧基硅烷(APTES)为改性剂,成功制备了氨基硅烷改性介孔硅球.并利用透射电子显微镜、能量色散X射线光谱仪和傅里叶变换红外光谱仪等对制备的介孔硅球进行了表征,同时考察了改性后的介孔硅对重金属铅的吸附效应.结果表明:通过改性处理,3-氨基丙基三乙氧基硅烷被成功接枝到介孔硅表面；氨基功能化介孔硅溶胶吸附剂对重金属Pb2+具有选择吸附特性,且吸附量随反应原料中APTES含量的提高呈现出相应的增加趋势.

| Abstract: | With mesoporous silicon as carrier material and APTES as modifier, the modified mesoporous silica sphere was successfully prepared. Its microstructures were characterized by transmission electron microscope(TEM), energy dispersive x-ray Detector(EDX) and Fourier transform infrared spectrum(FI-TR), and its adsorption on the heavy metal Pb was investigated. The results indicated that the APTES was grafted onto the surface of the mesoporous silica successfully, the modified mesoporous silicon had a selective adsorption characteristics on heavy metal Pb2+, and the adsorption capacity showed improving as the increase of the APTES in reactant. |
