中文摘要：

结合模板法和原位生长法制备了新型吸附与离子交换性能兼备的Ni-Fe（Ⅱ）普鲁士蓝/碳纳米管海绵，并通过稳定同位素铯模拟放射性核素研究了材料对Cs＋的去除效果。实验结果表明：复合材料很好地复制了聚氨酯海绵的三维开架多孔结构，在孔壁上沉积了大量碳纳米管，并在其表面生长了具有优异离子交换性能的Ni-Fe（Ⅱ）普鲁士蓝纳米颗粒，其占样品总量的1.38％。对Cs^＋的去除实验结果表明：Ni-Fe（Ⅱ）普鲁士蓝/碳纳米管海绵对Cs^＋有良好的去除能力；全谱等离子直接光谱仪（ICP）元素分析和穆斯堡尔谱研究表明，Ni-Fe（Ⅱ）普鲁士蓝中的K^＋与Cs^＋间发生了离子交换反应，材料对Cs＋的吸附容量为698μg/g。

英文摘要：

Ni-Fe（Ⅱ） Prussian blue/carbon nanotube sponge ,w hich has both adsorption and ionexchange properties , was synthesized by combining the template and insitu growth method .Then stable isotope of Cs was used to simulate radionuclide to study the adsorption effect of the composites .The results show that the sample has a three-dimensional porous structure as same as polyurethane foam . Moreover , the carbon nanotubes on the surface of sponge are successfully modified with Ni-Fe（Ⅱ ） Prussian blue .It shows that the ternary spongiform matrix contains 1.38% Ni-Fe（Ⅱ ） Prussian blue .Both ICP and Mossbauer spectrum analyses indicate that K^ ＋ in Ni-Fe（Ⅱ） Prussian blue is exchanged by Cs^＋ ,and the absorption capacity is 698 μg/g .
