摘要A macroporous silica-based 1,3-[(2,4-diethylheptylethoxy)oxy]-2,4-crown-6-calix[4]arene (Calix[4]arene-R14) supramolecular recognition polymeric composite, (Calix[4] + MODB)/SiO2-P, was synthesized. The synthesis was performed by impregnation and immobilization of Calix[4]arene-R14 and methyloctyl-2-dimethylbutanemide (MODB) molecules in the pores of a macroporous SiO2-P polymeric particle support with a mean diameter of 50 mu m. MODB was used to modify the Calix[4]arene-R14 through intermolecular interaction force. The static-state adsorption of sortie typical alkali metals and alkaline-earth metals such as Na(I), K(I), Cs(I), Rb(I), Sr(II), and Ba(II) onto (Calix[4] + MODB)/SiO2-P was investigated. The effects of contact time, HNO3 concentration in the range of 0.3-7.0 M, and temperature on the adsorption were examined. (Calix[4] + MODB)/SiO2-P exhibited strong adsorption ability and excellent selectivity for Cs(I) over all tested elements, which showed weak or almost no adsorption except for Rb(I). The adsorption onto (Calix[4] + MODB)/SiO2-P of the tested metals in HNO3 medium was exothermic. The thermodynamic parameters for the adsorptions of Cs(I) and Rb(I) were determined. It was found that, in 3.0 M HNO3, application of the (Calix[4] + MODB)/SiO2-P polymeric composite in the partitioning of Cs(I), one of the heat generators, from highly active liquid waste in the SPEC (strontium/cesium partitioning from HLW by extraction chromatography) process is promising.
