В качестве адсорбата использован азот особой чистоты. Были измерены изотермы адсорбции и рассчитаны удельная поверхность и пористость порошков, приведены результаты исследования морфологии. Поскольку графики БЭТ линейны в диапазоне относительных давлений от 0,05 до 0,35 Р/Р0, модель БЭТ хорошо применима для определения удельной площади поверхности образцов. Для образца АСД-4, по нашим расчетам, она составила 0,65 м2/г, для состава АСД-4 + 5 % V2O5 – 6 м2/г, для АСД-4 + 10 % V2O5 – 16 м2/г. То есть нанесение гидрогеля увеличивает удельную поверхность исходного АСД-4 более чем в десятки раз. Гранулометрический анализ показал, что после нанесения гидрогеля оба образца имеют достаточно узкое распределение частиц по размерам, что говорит о монодисперсности систем. Для АСД-4 средний размер частиц составил ~5÷7 мкм, для образца АСД-4 + 5 % V2O5 – около 9 мкм, для АСД-4 + 10 % V2O5 – 11 мкм. Установлено что благодаря слоистой структуре нанесенного ксерогеля в модифицированном образце появились мезопоры, радиус которых составил 35–40 Å. Показано, что наибольшей адсорбционной активностью обладает образец АСД-4 + 10 % V2O5 .</p></abstract><trans-abstract xml:lang="en"><p>The effect of the concentration of V2O5 vanadium pentoxide hydrogel applied in concentrations 5 and 10 % on ASD-4 grade aluminum, on its structural and adsorption properties was studied by the low-temperature nitrogen adsorption method. High-purity nitrogen was used as an adsorbate. Adsorption isotherms were measured with the specific surface area and porosity of powders calculated and results of morphology studies presented. Since BET diagrams are linear in the interval of relative pressures from 0.05 to 0.35 Р/Р0 , the BET model is well applicable for the calculation of the specific surface area of samples. According to our calculations, the specific surface area was 0.65 m2/g for ASD-4 sample, 6 m2/g for ASD-4 + 5 % V2O5 composition, and 16 m2/g for ASD-4 + 10 % V2O5. Therefore, hydrogel application increases the specific surface area of initial ASD-4 tenfold and more. Grain size analysis showed that both samples have a rather narrow particle size distribution after hydrogel application, which indicates the monodispesity of the system. The average particle size was ~5÷7 μm for ASD-4, ~9 μm for ASD-4 + 5 % V2O5 , and ~11 μm for ASD-4 + 10 % V2O5. It was established that mesopores 35 to 40 Å in radius appeared in the modified sample due to the layered structure of xerogel applied. It was shown that the ASD-4 + 10 % V2O5 sample exhibits the greatest adsorption activity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адсорбция</kwd><kwd>пористость</kwd><kwd>пентаоксид ванадия</kwd><kwd>ксерогель</kwd><kwd>мезопоры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adsorption</kwd><kwd>porosity</kwd><kwd>vanadium pentoxide</kwd><kwd>xerogel</kwd><kwd>mesopores</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по госбюджетной теме № АААА-А19-119031890028-0.</funding-statement><funding-statement xml:lang="en">The research was carried out on State-Funded Topic No. АААА-А19-119031890028-0.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Моррисон С.
