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。

Ni-Fe(Ⅱ) Prussian blue/carbon nanotube sponge ,w hich has both adsorption and ion-exchange properties , was synthesized by combining the template and in-situ 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 M?ssbauer spectrum analyses indicate that K + in Ni-Fe(Ⅱ) Prus-sian blue is exchanged by Cs+ ,and the absorption capacity is 698 μg/g .
