The studies on absorption behavior of calix[4]-bis-crown-6 chromatographic resin and its application to the separation of HLW

In this paper, to separation Cs(I) effectively from HLW, a kind of chromatographic rein was synthesized through immobiling calix4]-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.
