| Popis: | In this paper, to separation Cs(I) effectively from HLW, a kind of chromatographic rein was synthesized through immobiling calix[4]-bis-crown-6 on the macroporous polystyrene -divinylbenzene polymeric material. The synthesized chromatographic resin showed high ability to absorb Cs(I). While the radioactive elements Pu(III), Np(V), U(VI), Th(IV), as well as all of the fission and non-fission products showed almost no sorption towards chromatographic rein. The separation of Cs from HLW can be realized through adjusting the valence of Np and Pu or adding H2C2O4. All the results showed that the application of the new chromatographic rein to the analysis of HLW is possible. |
