采用EISA法,以PEG为主模板剂,根据辅助模板剂添加情况的不同,分别制备出S-N-A-T,S-NH3,S-TMAOH3种不同的硅基介孔材料.用X线衍射、氮气吸附脱附以及红外光谱等手段对3种材料进行了表征,在此基础上,通过吸附实验对比材料的吸附性能.表征结果显示,添加辅助模板剂后扩孔作用显著,大大改善产物的介孔结构,因此EISA法中添加辅助模板剂非常必要.其中以TMAOH为辅助模板剂合成的样品S-TMAOH介孔短程有序,各参数最佳.吸附研究表明,S-TMAOH对铅离子的吸附性能明显高于S-N-A-T和S-NH3,其吸附量受溶液pH值影响,在pH值为6.0时吸附容量最大.以TMAOH为辅助模板剂,制备的S-TMAOH材料对铅离子具有良好的吸附性和再生性.
