Проведен сравнительный анализ различных подходов к интенсификации массообменных процессов, в том числе с учетом надмолекулярной организации экстрагентов. Основное внимание уделено изменениям структурных характеристик этанола, воды и трибутилфосфата под воздействием переменного частотно-модулированного сигнала. Показано, что электрофизическая обработка приводит к снижению динамической вязкости на 14–20 %, уменьшению коэффициента поверхностного натяжения до 23 % и увеличению площади свободной поверхности жидкости. Это обусловливает рост коэффициентов диффузии и массопередачи, способствуя ускорению экстракционных процессов. Экспериментальные данные подтверждают, что предварительная обработка компонентов системы электрическим полем повышает проницаемость через полупроницаемые мембраны, усиливает капиллярный подъем и изменяет параметры осмотического давления. Установлено, что наибольшую эффективность демонстрирует селективное воздействие на один из компонентов системы — трибутилфосфат или водный раствор лантаноидов — в отличие от одновременной обработки обеих фаз. Коэффициент распределения при этом увеличивается до 69 %, что свидетельствует о перспективности такого подхода для интенсификации процессов экстракции. Полученные результаты имеют значимое прикладное значение для оптимизации технологий разделения в химической промышленности. Авторы подчеркивают необходимость дальнейших исследований по уточнению оптимальных параметров электрофизического воздействия и расширению круга исследуемых экстрагентов.</p></abstract><trans-abstract xml:lang="en"><p>The study examines the influence of alternating electric fields on the physicochemical properties of polar liquids and the efficiency of extraction processes involving them. A comparative analysis of various approaches to the intensification of mass transfer processes is presented, with particular focus on the supramolecular organization of extractants. Special attention is given to structural changes in ethanol, water, and tributyl phosphate under the action of a modulated alternating current signal. It is shown that electrophysical treatment reduces dynamic viscosity by 14–20%, decreases surface tension by up to 23%, and increases the free surface area of the liquids. These changes enhance diffusion and mass transfer coefficients, thus accelerating extraction processes. Experimental results confirm that preliminary treatment of system components with electric fields increases permeability through semipermeable membranes, intensifies capillary rise, and affects osmotic pressure parameters. It is established that the most effective approach involves selective treatment of a single system component—either tributyl phosphate or the aqueous solution of rare earth elements—rather than simultaneous treatment of both phases. The distribution coefficient increases by up to 69%, indicating the high potential of this method for intensifying extraction processes. These findings have significant practical implications for optimizing separation technologies in the chemical industry. The authors emphasize the need for further research to define optimal electrophysical treatment parameters and to extend the range of investigated extractants.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экстрагирование</kwd><kwd>экстракция</kwd><kwd>воздействие переменного электрического поля</kwd><kwd>полярные экстрагенты</kwd><kwd>изменения надмолекулярной структуры</kwd><kwd>этиловый спирт</kwd><kwd>NМП</kwd></kwd-group><kwd-group xml:lang="en"><kwd>solid extraction</kwd><kwd>extraction</kwd><kwd>effects of alternating electric field</kwd><kwd>polar extractants</kwd><kwd>changes in the supramolecular structure</kwd><kwd>ethyl alcohol</kwd><kwd>NMP</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">Романков П.Г.
