首先合成了一种新型双功能性离子液体1-甲基-3-(3′-磺酸丙基)咪唑十二烷基磺酸盐([PMIM(SO3H)][C12SO3]),并采用FT-IR、1HNMR和13CNMR对其结构进行了表征；进一步以该离子液体为模板剂和酸源,以正硅酸乙酯(TEOS)为硅源,通过溶胶-凝胶法制备出介孔SiO2,利用TGA和FT-IR研究了介孔材料的形成过程,采用SAXRD、SEM、TEM和氮气等温吸附-脱附等手段对介孔材料的结构形貌进行了表征,并研究了其对Pb2+的吸附性能。结果显示,以[PMIM(SO3H)][C12SO3]为模板剂和酸源制备的介孔SiO2其比表面积、孔容、平均孔径大小分别为1010m2/g、0.95cm3/g、3.25nm,其对重金属Pb2+有很好的吸附性能。

A novel bifunctional ionic liquid 1-methyl-3-(3-sulfopropyl )-imidazolium n-dodecayl sulfonate ([PMIM(SO3 H)][C12 SO3 ])was conveniently synthesized,and the structure was determined by FT-IR,1 H NMR and 13 C NMR,respectively.Furthermore,mesoporous silica was prepared from ethyl silicate (TEOS)as silica source and the obtained ionic liquid as acid source and template by traditional sol-gel methods.The forma-tion of the mesoporous material was characterized by TGA and FT-IR.Several methods such as SAXRD,SEM, TEM and nitrogen adsorption-desorption isotherms were employed to characterized the morphological structure and properties of mesoporous silica.The experiment on Pb2+,one kind of heavy metal ion,adsorption was ap-plied so as to detect the property of the material.The resultant mesoporous silica material exhibited the specific surface area of 1 010 m2/g,the pore volume of 0.95 cm3/g and the average pore diameter size of 3.25 nm,re-spectively,while the mesoporous silica has a good adsorption property for heavy metal ion of Pb2+.
