| 英文摘要 | A macroporous silica-based 1,3-[(2,4-diethyl-heptylethoxy)oxy]-2,4-crown-6-calix[4]arene (Calix[4]arene-R14) supramolecular recognition polymeric composite, (Calix[4]+Oct)/SiO(2)-P, was synthesized. It was performed by impregnating and immobilizing Calix[4]arene-R14 and n-octanol into the pores of the macroporous SiO(2)-P particles support. n-Octanol was used to modify Calix[4]arene-R14 through hydrogen bonding. The effect of eight typical fission products contained in highly active liquid waste (HLW) on the adsorption of Cs(I), one of the heat generators, was investigated at 298 K by examining the effect of contact time and the HNO(3) concentration in a range of 0.3-7.0 M. (Calix[4]+Oct)/SiO(2)-P showed excellent adsorption ability and high selectivity for Cs(I) at 4.0 M HNO(3) over the tested elements. The partitioning of Cs(I) from a simulated HLW was operated by (Calix[4]+Oct)/SiO(2)-P packed column. Cs(I) was able to be effectively eluted by water and separated from the tested metals. It is demonstrated that (Calix[4]+Oct)/SiO(2)-P is promising to apply in chromatographic separation of Cs(I) from HLW.
