新型Ni-Fe（Ⅱ）普鲁士蓝／碳纳米管海绵去除 Cs ＋的研究
Study of Removing Cs+ by Ni-Fe(Ⅱ) Prussian Blue/Carbon Nanotube Sponge
摘要
Abstract
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 Mössbauer spectrum analyses indicate that K + in Ni-Fe(Ⅱ) Prus-sian blue is exchanged by Cs+ ,and the absorption capacity is 698 μg/g .关键词
