Изучение влияния внешнего стационарного магнитного поля на процесс фотокаталитической деградации метиленового синего в присутствии ультрадисперсных частиц оксида цинка и при воздействии ультрафиолетового излучения. </p></sec><sec><title>Методы</title><p>Методы. Определение степени фотохимической деградации красителя метиленового синего методами оптической спектрометрии проводилось с помощью комплекса спектрофотометрического оборудования на базе спектрофотометров СФ-2000 и HR-2000. Характеризация размерного распределения фотокаталитических частиц оксида цинка с помощью атомно-силовой микроскопии SmartSPM (AIST-NT), элементного состава на сканирующем электронном микроскопе JEOL 6610LV с приставкой энергодисперсионного анализа (Oxford), структуры и фазового состава с помощью рентгенофазового анализа на рентгеновском порошковом дифрактометре EMMA (Австралия). </p></sec><sec><title>Результаты</title><p>Результаты. Диспергированные частицы оксида цинка, синтезированные золь-гель-методом, имеют размер от 30 до 120 нм со средним количественным размером 60 нм. Кристаллографическая структура фотокатализатора по межплоскостным расстояниям соответствует монооксиду цинка гексагональной сингонии. Анализ данных процесса фотокаталитической деградации метиленового синего показывает, что фотоактивность частиц оксида цинка значительно увеличивается в условиях действия внешнего стационарного магнитного поля. Так установлено, что в постоянном магнитном поле величиной 0,56 Тл фотокаталитическая активность частиц ZnO увеличивается на 20%. </p></sec><sec><title>Заключение</title><p>Заключение. На основании полученных экспериментальных данных можно сделать вывод, что введение постоянного магнитного поля позволяет значительно увеличить скорость фотокаталитического разложения метиленового синего. Представленные результаты могут быть применены для промышленной очистки воды от загрязнителей, где, варьируя величину магнитного поля, можно регулировать интенсивность разложения вредных органических веществ. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Study of the influence of an external stationary magnetic field on the process of photocatalytic degradation of methylene blue in the presence of ultrafine particles of zinc oxide and under the influence of ultraviolet radiation. </p></sec><sec><title>Methods</title><p>Methods. Determination of the degree of photochemical degradation of the dye methylene blue by optical spectrometry using a set of spectrophotometric equipment based on SF-2000 and HR-2000 spectrophotometers. Characterization of the size distribution of photocatalytic zinc oxide particles using SmartSPM atomic force microscopy (AIST-NT), elemental composition on a JEOL 6610LV scanning electron microscope with an energy dispersive analysis attachment </p><p>(Oxford), structure and phase composition using X-ray phase analysis on an EMMA X-ray powder diffractometer (Australia). </p></sec><sec><title>Results</title><p>Results. Dispersed zinc oxide particles synthesized by the sol-gel method have a size from 30 to 120 nm with an average quantitative size of 60 nm. The crystallographic structure of the photocatalyst at interplane distances corresponds to the zinc monoxide of the hexagonal syngony.   An analysis of the data on the process of photocatalytic degradation of methylene blue shows that the photoactivity of zinc oxide particles increases significantly under the action of an external stationary magnetic field. Thus, it was established that in a constant magnetic field of 0,56 Tl, the photocatalytic activity of ZnO particles increases by 20%. </p></sec><sec><title>Conclusion</title><p>Conclusion. Based on the experimental data obtained, it can be concluded that the introduction of a constant magnetic field can significantly increase the rate of photocatalytic decomposition of methylene blue. The presented results can be applied to industrial water purification from pollutants. By changing the magnitude of the magnetic field, it is possible to control the intensity of decomposition of pollutants. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>оксид цинка</kwd><kwd>фотокаталитическая активность</kwd><kwd>спектрофотометрия</kwd><kwd>стационарное магнитное поле</kwd><kwd>атомно-силовая микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>zinc oxide</kwd><kwd>photocalytic activity</kwd><kwd>spectrophotometry</kwd><kwd>stationary magnetic field</kwd><kwd>atomic force microscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского фонда фундаментальных исследований в рамках научного проекта № 20-02-00599,  а также при поддержке Министерства образования и науки РФ (г/з 2020 № 0851-2020-0035), в рамках реализации программы стратегического академического лидерства «Приоритет-2030» (Соглашение № 075-15-2021-1213).</funding-statement><funding-statement xml:lang="en">The reported study was funded by RFBR, project number 20-02-00599 А.
