To separate Y-90 from the fission product Sr-90-Y-90 group, a silica-based TODGA/SiO2-P adsorbent was prepared by impregnating N,N,N',N'-tetraoctyl-3-oxapentane-1,5-diamide (TODGA) extractant into the macroporous SiO2-P support with a mean diameter of 60 mu m. The adsorption behavior of Sr(II) and Y(III) onto TODGA/SiO2-P adsorbent from HNO3 solution and their mutual separation were investigated. Under the experimental conditions, this adsorbent showed high adsorption affinity to Y(III) and weak adsorption to Sr(II). It was found that the adsorption process of Y(III) could be expressed by both of Langmuir monomolecular layer adsorption mode and the pseudo-second order model. From the results of stability experiments, it became clear that TODGA/SiO2-P adsorbent is stable in 3 M HNO3 solution for 1 month contact time at 298 K. Using a column packed with TODGA/SiO2-P adsorbent, Sr(II) and Y(III) were eluted by distilled water and diethylenetriamine pentaacetic acid (DTPA) solution, respectively. The separation of Y(III) from Sr(II)-Y(III) group was achieved successfully. (C) 2012 Elsevier B.V. All rights reserved.
