摘 要:在Fe3O4磁性纳米粒子表面复盖一层磷酸化聚乙烯醇制备了一种用于从水相选择性分离铀酰的复合型磁性纳米粒子。用平衡吸附法研究了纳米粒子对铀酰的吸附性能和选择识别能力,且探讨了实验条件对纳米粒子吸附性能的影响。结果表明在竞争金属离子存在下,纳米粒子对铀酰具有较高的吸附能力和选择识别能力,且可以循环使用。A new composite type of magnetic nanoparticles for the selective separation of uranyl from aqueous solution was prepared by coating phosphorylated polyvinyl alcohol on the surface of Fe304 nanoparticles. The adsorption property and selective recognition ability of the nanoparticles were studied by equilibrium-adsorption method. The influence of experimental conditions to the adsorption property was also investigated. The results showed that in the presence of competitor metal ions, the nanoparticles had high adsorption and selective recognition ability, and the nanoparticles could be used repeatedly.
