中文摘要：

采用表面离子印迹技术,以铷（I）离子为印迹离子,3-氨基丙基-三乙氧基硅烷为功能单体,纳米TiO2/SiO2为载体,制备了铷（I）离子印迹聚合物（IIP）。详细研究了铷离子印迹聚合物对铷（I）的吸附性能和选择性。结果表明：此印迹聚合物在pH值为6时能定量吸附Rb＋离子,对Rb＋离子的最大吸附容量为16.51 mg·g-1,60min达到吸附平衡且重复性好。与非印迹聚合物比较,该铷（I）离子印迹聚合物对Rb＋离子具有较好的识别性和选择性。

英文摘要：

A rubidium ion imprinted nanometer TiOz/SiO2 composite material was prepared by the surface imprinting technique using Rb（I） ion as the template and 3-Aminopropyltriethoxysilane as the functional monomer. The adsorption and selectivity of Rb（I） on ion-imprinted polymers were studied in detail. The results showed that the sorption of rubidium was achieved in 60 rain and the maximum static adsorption capacity was 16.51 mg·g-1. When the rubidium imprinted polymer was repeatedly used, its adsorption capacity was kept. The selectively adsorbed amount of Rb（I） ion on rubidium imprinted polymer is higher than those of all other ions studied.
