Abstract
Surface modified adsorbent mesoporous silicate MCM-41 has been prepared by grafting thiol containing functional group onto mesoporous silicate MCM-41. XRD, N2 adsorption/desorption measurements, SEM, FT-IR, thermogravimetry and elemental analysis have been made to confirm the ordered mesoporous framework and the functionalization of the thiol groups. Sorption of 18 metal ions on this sorbent have been studied and discussed. Chromatographic separation of Rb(I)–U(VI)–Sr(II)–Zr(IV), has been achieved on column of this sorbent.
