英文摘要A new macroporous silica-based-polymer (SiO2-P) soft ligand composite material, 2,6-bis(5,6-di(iso-butyl)-1,2,4-triazine-3-yl)pyridine (BDIBTP/SiO2-P), was synthesized by impregnation and immobilization of BDIBTP and 1-octanol molecules into the pores of the SiO2-P particles. The impact of some typical alkali metal and alkaline earths Cs(I), Na(I), K(I), Rb(I), Sr(II), and Ba(II) containing in highly active liquid waste (HLW) on the adsorption of Pd(II) onto BDIBTP/SiO2-P was studied. It was performed by examining the effects of contact time and the HNO3 concentration in the range of 0.37.0 M. BDIBTP/SiO2-P showed strong adsorption ability and high selectivity for Pd(II) over all the tested metals. The chromatographic partitioning of Pd(II) from a simulated HLW solution was conducted by BDIBTP/SiO2-P packed column. Pd(II) was effectively eluted with 0.2 M thiourea0.1 M HNO3. The others showed no adverse impact on separation of Pd(II). The results are beneficial to partitioning of minor actinides and Pd(II) together from HLW by BDIBTP/SiO2-P in the MPS process developed.
