Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CHELATES -- AMINO-CONTAINING POLYMER -- N-2-SULFOETHYL CHITOSAN Аннотация: A new procedure was developed for preparation of chelate amino-containing polymer N-2-sulfoethyl chitosan by synthesis in a gel through the reaction between chitosan and sodium 2-bromoethanesulfonate, yielding a polymer with the degree of substitution of up to 0.5. The structure of the resulting polymers was confirmed by 1H NMR spectroscopy. The sorption characteristics with respect to transition and alkaline-earth metal ions were determined for the cross-linked polymers \\\\expert2\\NBO\\Russian Journal of Applied Chemistry\\2013, v. 86, N 2, p.269.pdf |
