摘　　要：以1,4-亚苯基二(丙基氨基甲酸酯基)桥联硅烷(AM-Si)和正硅酸乙酯(TEOS)为硅源,十六烷基三甲基溴化铵(CTAB)为模板剂,碱性条件下合成了一种新型功能化桥键介孔氧化硅(AM-PMOs),用X射线粉末衍射(SAXRD)、扫描电镜(SEM)、透射电镜(TEM)、热重(TG)、红外光谱(IR)、N2吸附-脱附等手段对材料进行表征.并对Cd2+进行吸附性能测试,静态饱和吸附容量达到62.89mg.g-1.A novel functional periodic mesoporous organosilicas bridged via 1,4-phenylene bis（propylcar- bamate} were synthesised via condensation using tetraethyl orthosilicate （TEOS） and 1,4-phenylene bis（ （3- {triethoxysilyl）propyl）carbamate} （AM-Si） as framework precursors. The synthesis was performed under the alkaline condition in the presence of cetyltrimethylammonium bromide （CTAB）. The materials are char- acterized by FT-IR,SAXRD, TG, TEM,SEM and N2adsorption desorption. The adsorption behavior of the AM-PMOs toward Cd2＋ was studied. The statically saturated sorption capacity is 62.89 mg · g-1.
