   <abstract xml:lang="ru">
    <p>Разработан новый эффективный сорбент на основе хлопковой целлюлозы в результате ее химического модифицирования. Процесс модифицирования состоит из двух стадий, включающих последовательную обработку целлюлозы эпихлоргидрином и   диэтилентриамином. Для полученного сорбента приведены оптимальные условия модифицирования, позволяющие достичь наиболее высоких значений сорбционной емкости при извлечении ионов железа(II) и меди(II) из водных растворов. Были исследованы кинетика и равновесие сорбции ионов тяжелых металлов в системе «целлюлозный сорбент – водный раствор сульфата металла» для исходной и модифицированной хлопковой целлюлозы. Обработка результатов кинетического эксперимента свидетельствует, что наиболее корректно кинетика сорбции ионов металлов описывается в рамках модели кинетики псевдо-второго порядка. Изотермы сорбции ионов тяжелых металлов наглядно свидетельствуют о росте сорбционной емкости модифицированного сорбента по сравнению с исходным. Обработка экспериментальных изотерм в рамках модели Ленгмюра позволила определить величины максимальной сорбционной емкости (А∞) исходной хлопковой целлюлозы и целлюлозы, модифицированной диэтилентриамином, по отношению к ионам Cu(II) и Fe(II). Было обнаружено, что А∞ модифицированного сорбента примерно в 3 раза превышает предельную сорбционную емкость нативной хлопковой целлюлозы по отношению к ионам железа(II) и меди(II). Сравнение ИК-спектров образцов исходной целлюлозы и целлюлозы, обработанной диэтилентриамином, свидетельствует о произошедших в ходе химического модифицирования изменениях. Представлены СЭМ изображения, отражающие изменения структуры поверхности модифицированного сорбента по сравнению с исходным.</p>

    <p>The authors have developed new effective sorbent based on chemically modified cotton cellulose. The modification process consists of two stages, including sequential treatment of cellulose with epichlorohydrin and diethylene triamine. The authors present &#13;
the optimal modification conditions for the obtained sorbent. It allows ones’ to achieve the highest values of sorption capacity for the extraction of iron(II) and copper(II) ions from aqueous solutions. The authors investigated the kinetics and equilibrium of heavy metal ion sorption in the system &quot;cellulose sorbent - aqueous solution of metal sulphate&quot; for original and modified cotton cellulose. Processing of the kinetic experiment results indicates that the kinetics of metal ion sorption is described most correctly in the framework of the pseudo-second-order kinetics model. Isotherms of heavy metal ions sorption clearly indicate the growth of sorption capacity for the modified sorbent in comparison with the original one. Processing of experimental isotherms within the Langmuir model made it possible to determine the values of the maximum sorption capacity (A∞) of original and modified with diethylenetriamine cotton cellulose with respect to Cu(II) and FE(II) ions. It was found that the A∞ of the modified sorbent was about 3 times higher than the ultimate sorption capacity of original cotton cellulose towards iron(II) and Cu(II) IONS. Comparison of IR spectra of the original cellulose samples and cellulose treated with diethylenetriamine indicates the changes that occurred during chemical modification. The paper presents SEM images showing the changes in the surface structure of the modified sorbent compared to the original one.</p>
