Modified mesoporous cerium(III) silicates, have been prepared with various mole ratios of Si/Ce (10, 20, 40, 80) by using cetyltrimethylammonium bromide (CTAB) as template and characterized by powder X-ray diffraction, N2 adsorption-desorption measurment, SEM, FT-IR, thermogravimetry to confirm the mesoporous structure. Sorption behavior for 23 metal ions on this adsorbenthave been studied and discussed. Separation of Rb(I)–U(VI), Tl(I)–U(VI) and Co(II)– U(VI) have been developed on columns of this adsorbent.
