When the PPVB was selected as adsorbing material, which was prepared with polyvinyl alcohol phosphate ester containing 14.22% phosphorus, adsorption capacity of trivalent rare earth ions and241 Am3+ on it was investigated.

• 综合吸附能力，机械性能等多方面的因素，选择了磷含量为14.；22%25的磷酸酯化聚乙烯醇为原料制备得到的PPVB为吸附材料，考虑到稀土元素与镅的物理化学性质相似，因此实验中在对稀土离子吸附性能研究的基础上，再对~(241)Am进行放射性去污实验。
