Иониты были получены модификацией промышленного полиакрилонитрильного волокна диэтилентриамином и триэтилентетраамином, преимущественно содержали функциональные группы R-CO-NH-(CH2CH2NH)nH (n = 2 или 3) и небольшое количество карбоксильных групп. Из полученных данных рассчитана сорбция Ni2+, Со2+, Сu2+ и Ca2+ ионитами в зависимости от рН среды. Установлено, что исследованные иониты с высокой селективностью сорбируют ионы тяжелых металлов в широком интервале кислотности растворов (рН 2–9) благодаря образованию металл-полимерных комплексов с полиаминными функциональными группами. Максимальная сорбционная емкость составляет 1,5–2,7 и 4–5 мэкв/г для ионитов с n = 2 и 3 соответственно.</p></abstract><trans-abstract xml:lang="en"><p>Curves of potentiometric titration of fully protonized fibrous ion exchangers with potassium hydroxide against the background of 1 M KCl in the presence of chlorides of Ni2+, Со2+, Сu2+ and Ca2+ were obtained. The ion exchangers were synthesized by modifying of industrial polyacrylonitrile fiber with diethylenetriamine and triethylenetetraamine and predominantly contained functional groups R-CO-NH- (CH2CH2NH)nH (n = 2 or 3) and a small amount of carboxyl groups. The sorption of Ni2+, Со2+, Сu2+ и Ca2+by ion exchangers was calculated from the data obtained depending on the pH of the medium. It was found that the investigated ion exchangers with high selectivity sorb heavy metal ions in a wide range of acidity of solutions (pH 2–9) due to the formation of metal-polymer complexes with polyamine functional groups. The maximum sorption capacity is 1.5–2.7 and 4–5 meq/g for ion exchangers with n = 2 and 3, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>волокнистые аниониты</kwd><kwd>сорбция тяжелых металлов</kwd><kwd>металл-полимерные комплексы</kwd><kwd>потенциометрическое титрование ионитов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fibrous anion exchangers</kwd><kwd>sorption of heavy metals</kwd><kwd>metal-polymer complexes</kwd><kwd>potentiometric titration of ion exchangers</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">Синтез аминокарбоксильных ионитов на основе полиакрилонитрильного волокна / И.
