Заглавие : New hybrid chelating sorbents with grafted 3-aminopropionate groups based on mixed silicon, aluminum, titanium, or zirconium oxides [Electronic resource] Место публикации : Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya). - 2005. - Vol. 54, № 8. - С. 1836-1841 Систем. требования: http://www.springerlink.com/content/d2134945547008v4/fulltext.pdf Примечания : 24.10.2011 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: 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 1H 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 °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 Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Yatluk, Yu.
