Abstract:

A series of new hybrid organo-inorganic sorbents with the 3-aminopropionate chelating group was synthesized. The synthesis includes the copolycondensation (sol-gel method) of tetraethoxysilane, 3-aminopropyltriethoxysilane, and several modifiers (MeSi(OEt)(3), EtSi(OEt)(3), Ti(OEt)(4), AlONO3, ZrOCl2) followed by carboxyethylation with acrylic acid. The obtained chelating sorbents were characterized by elemental analysis, FT-IR and H-1 NMR spectroscopy, and thermogravimetry. The N-carboxylated sorbents have a higher sorption capacity with respect to metal ions (0.5-0.9 mmol g(-1), pH 6.3, NH4OAc, 20 degrees C) than the starting sorbents with the primary amino group (0.05-0.2 mmol g(-1)) and manifest high selectivity for copper(II) ion extraction.
