Определены ионообменные емкости по аминои карбоксильным группам, зарегистрированы фурье ИК спектры поглощения полученных образцов. Методом жидкостной хроматографии изучена динамика изменения во времени концентрации ГА в аминирующем растворе (без нитрона) и в процессе аминирования нитрона. Концентрация ГА в аминирующем растворе (без нитрона) быстро падает со временем, снижаясь до нуля за 6 ч, и за 2 ч – в присутствии нитрона. Более быстрое снижение концентрации ГА в растворе в присутствии нитрона обусловлено переходом ГА в объем волокна с образованием амидоксимных фрагментов. Присутствие амидоксимов в аминированном волокне подтверждено данными ИК спектроскопии по полосам поглощения при 940 и 912 cм–1, относящимся к деформационному колебанию NH2-групп и валентному колебанию N–O соответственно.</p><p>(Представлено академиком В.

The ion exchange capacities for amino and carboxyl groups were determined, and Fourier IR transmission spectra of the obtained samples were recorded. The dynamics of changes in the concentration of HA in the aminating solution (without nitron) and in the process of nitron amination over time were studied using liquid chromatography. It was found that the concentration of HA in the aminating solution (without nitron) rapidly decreases with time, decreasing to zero in 6 hours and in 2 hours, respectively, in the presence of nitron. A more rapid decrease in the concentration of HA in the solution in the presence of nitron is due to the transition of HA into the fiber volume with the formation of amidoxime fragments. The presence of amidoximes in the aminated fiber is confirmed by IR spectroscopy data for the absorption bands at 940 and 912 cm–1, related to the deformation vibration of NH2-groups bond and the stretching vibration of N–O, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Нитрон-Д</kwd><kwd>аминирование</kwd><kwd>диэтилентриамин</kwd><kwd>гидроксиламин</kwd><kwd>волокнистый анионит ФИБАН АК-22</kwd><kwd>ионообменная емкость по аминои карбоксильным группам</kwd><kwd>амидоксимы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Nitron-D</kwd><kwd>amination</kwd><kwd>diethylenetriamine</kwd><kwd>hydroxylamine</kwd><kwd>fibrous anion exchange resin FIBAN AK-22</kwd><kwd>ion exchange capacity for amino and carboxyl groups</kwd><kwd>amidoximes</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Химически активные волокна для очистки воздушных и водных сред ФИБАН. – URL: https://ifoch.by/research/fiban/ (дата обращения: 03.01.2025).</mixed-citation><mixed-citation xml:lang="en">Chemically active fibers for air and water purification FIBAN (in Russian). – URL: https://ifoch.by/research/fiban/ (date of access: 03 January 2025).</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Механизм каталитического влияния гидроксиламина на реакцию полиакрилонитрила с азотсодержащими основаниями / Д.
