Аннотация:
New anion exchangers with the trimethylammonium functional group were prepared as a result of three-step synthesis involving the acylation of styrene-divinylbenzene copolymer with 25% cross-linking, the reductive amination of carbonyl groups, and subsequent methylation. Two methods of reductive amination were studied, and optimal conditions for this process were chosen. Chromatographic properties of the adsorbents were examined in a mode of ion chromatography with suppressed background conductivity and conductometric detection. The obtained anion exchangers demonstrated good selectivity, and the maximum efficiency was 30000 TP/m. © 2011 Allerton Press, Inc.
