Abstract

To separate Y(III) from the Sr(II)-Y(III) mixture, (DtBuCH18C6+Dodec)/SiO₂-P was synthesized by successive impregnation and fixing the DtBuCH18C6 and its molecule modifier 1-Dodecanol onto SiO₂-P. This adsorbent showed a high adsorption affinity to Sr(II) and a weak adsorption affinity to Y(III). Kinetic data were successfully modeled using pseudo-second-order kinetics. The adsorption of Sr(II) could be expressed by the Langmuir monomolecular layer adsorption model and was governed by chemisorption. The breakthrough curve of Sr(II) had S-shaped profile, and the loaded Sr(II) ions were successfully eluted with an eluent of H₂O using a column packed with the adsorbent. The separation of Y(III) from Sr(II)-Y(III) mixture was achieved successfully.
