Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): AMINO POLYMER -- PYRIDYLETHYLPOLYETHYLENIMINE Аннотация: A method was developed for preparing a chelating amino polymer, pyridylethylpolyethylenimine with maximal degree of substitution, by polymer-analogous transformations of branched polyethylenimine in reaction with 2-vinylpyridine. The ability of cross-linked pyridylethylpolyethylenimine with the degree of substitution of 0.32 to sorb Cu2+, Ni2+, Co2+, Zn2+, Cd2+, Mn2+, and Pb 2+ ions present simultaneously in solution was evaluated. In an ammonium acetate sorption system (pH 3.5-4.0), the sorbent selectively interacts with Cu(II) ions \\\\expert2\\nbo\\Russian Journal of Applied Chemistry\\2013, v. 86, N 9, p.1383.pdf |
