摘要：

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, N-2 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.
