摘要
Linear poly(NIPAAm-co-X), with X being AAc or 4-VP, was synthesized by means of gamma radiation induced polymerization in tetrahydrofuran (THF). The binary copolymers obtained are possessed of water-soluble, temperature sensitivity. It was also found that raising pH leads to a higher LCST when X is AAc. Prepared copolymers were used to concentrate metal ions, such as UO(2)(i)(2+)cRE(3+) and Cr(VI) in dilute aqueous solution, which showd obvious concentration effect. The conditions of ion concentration were given and the mechanism was discussed preliminary.
