Структура целлюлозы и модифицированной наноцеллюлозы изучалась методами Рамановской спектроскопии, ИК (инфракрасной) спектроскопии, РФА (рентгенофазный анализ), СЭМ (сканирующая электронная микроскопия). Полученное повышение кристалличности НТЦ (нановолокнистая целлюлоза) было подтверждено анализом РФА. Это указывает на то, что целлюлоза была связана с удалением аморфных частей. В результате РФА перекрытие на рентгенограммах НТЦ происходило даже в области интенсивных линий. В образце, полученном методом ИК спектроскопии, обнаружено наличие групп (3413,12 см−1; 2918,34 см−1; 1373,30 см−1; 617,52 см−1), соответствующих природе НТЦ. Сильное поглощение при 1429,8 см−1 в спектре КМЦ (карбоксилметилцеллюлозы) выявило группы -COOН, что указывает на успешное карбоксилирование целлюлозы. Изучены морфологическая поверхность, средний размер частиц и структура образцов. В результате сравнительного анализа морфологических структур выявлена характерная для волокон упорядоченная нитевидная структура нановолокнистой целлюлозы и пористая структура КМЦ с измененной поверхностью и неравномерными волокнами.</p><p>Разработанный способ получения модифицированной целлюлозы из биомассы не требует многостадийной обработки по сравнению с традиционными методами и безопасен для окружающей среды. Показано, что можно получить качественную целлюлозу в одну стадию без использования реагентов, содержащих серу и хлор, высокого давления и больших затрат воды.</p></abstract><trans-abstract xml:lang="en"><p>This work describes the production of nanocellulose by removing lignin from biomass by the peroxide method in the presence of an H2SO4 catalyst and the study of its physicochemical properties. The structure of cellulose and modified nanocellulose was studied using Raman spectroscopy, IR (infrared) spectroscopy, X-ray diffraction, and SEM (scanning electron microscopy). The resulting increase in the crystallinity of NFC (nanofibrous cellulose) was confirmed by X-ray diffraction analysis. This indicates that cellulose was associated with the removal of amorphous parts. As a result of X-ray diffraction, overlap on NFC radiographs occurred even in the area of intense lines. In the sample obtained by IR spectroscopy, the presence of groups (3413.12 cm−1; 2918.34 cm−1; 1373.30 cm−1; 617.52 cm−1) corresponding to the nature of NFC was detected. Strong absorption at 1429.8 cm−1 in the spectrum of CMC (carboxylmethylcellulose) revealed –COOH groups, indicating successful carboxylation of cellulose. The morphological surface, average particle size and structure of the samples were studied. As a result of a comparative analysis of morphological structures, an ordered filamentous structure of nanofibrous cellulose characteristic of fibers and a porous structure of CMC with a modified surface and uneven fibers were revealed. The developed method for producing modified cellulose from biomass does not require multi-stage processing compared to traditional methods and is safe for the environment. It has been shown that it is possible to obtain high-quality cellulose in one stage without the use of reagents containing sulfur and chlorine, high pressure and high water consumption.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биомасса</kwd><kwd>рисовая шелуха</kwd><kwd>остатки древесины сосны</kwd><kwd>сернокислотный катализатор</kwd><kwd>целлюлоза</kwd><kwd>кислотный гидролиз</kwd><kwd>модифицированная наноцеллюлоза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biomass</kwd><kwd>rice husk</kwd><kwd>pine wood residues</kwd><kwd>sulfuric acid catalyst</kwd><kwd>cellulose</kwd><kwd>acid hydrolysis</kwd><kwd>modified nanocellulose</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">Moon R.J., Martini A., Nairn J., Simonsen J., Youngblood J.
