摘要: Mesoporous aluminosilicates, have been prepared with various mole ratios of Si/Al and Cethyltrimethylammonium bromide (CTAB). They characterized by XRD, nitrogen adsorption/desorption measurements, FT-IR thermogravimetry. Adsorption behavior heavy metal ions on this adsorbent studied discussed. The results show that incorporation aluminum in the framework mesoporous MCM-41 has transformed it into an effective cation exchanger. Kd values several increased. Separation Sr(II)–Ce(III), Sr(II)–U(VI) Cd(II)–Ce(III) developed columns novel
