However, the process of LDH synthesis, depending on the LDH chemical composition, can take from tens of hours to several days. It was previously identified that ultrasound exposure during the LDH production significantly reduces the synthesis time, and LDHs produced in this way are interesting in relation to the study of their physicochemical properties and sorption capacity. In this work, the authors produced Mg/Fe LDHs in nitrate form by the traditional method and by the combined action of ultrasound and increased hydrostatic pressure. The resulting samples are characterized by a complex of physicochemical methods of analysis, including scanning electron microscopy (SEM), infrared spectroscopy (IR), X-ray phase analysis (XRD), and thermal gravimetric analysis (TGA) with differential scanning calorimetry (DSC). Experiments were carried out to study the sorption capacity of the obtained Fe/Mg LDH samples in relation to chromate ions under normal conditions and under the influence of ultrasound, including in combination with increased hydrostatic pressure. A photoelectric photometer was used to obtain and analyze data with quantitative values of the sorption process. Data of comprehensive analysis of the finished product indicate that the synthesized material is a Mg/Fe layered double hydroxide. X-ray phase analysis identified that the LDH synthesis using ultrasound and pressure increases the crystallinity degree of the finished product. It has been found that the sorption properties of LDHs produced by the conventional method and LDHs produced under the influence of ultrasound and pressure are different. In Mg/Fe LDHs synthesized by the conventional method, chromate sorption proceeds better than in samples synthesized using ultrasonic treatment in combination with increased hydrostatic pressure. The study shows that the sorption process of the examined LDH samples is described by different mathematical models.</p></abstract><trans-abstract xml:lang="ru"><p>Слоистые двойные гидроксиды (СДГ) можно отнести к классу перспективных материалов благодаря простоте синтеза, а также обширной сфере их применения. Однако процесс синтеза СДГ в зависимости от их химического состава может занимать от десятков часов до нескольких суток. Ранее было установлено, что воздействие ультразвуком в процессе получения СДГ значительно сокращает время синтеза, а полученные таким способом СДГ интересны в отношении изучения их физико-химических свойств, а также сорбционной способности. В работе получены Mg/Fe СДГ в нитратной форме традиционным методом, а также при совместном действии ультразвука и повышенного гидростатического давления. Полученные образцы охарактеризованы с помощью комплекса физико-химических методов анализа, включающих сканирующую электронную микроскопию (СЭМ), инфракрасную спектроскопию (ИК), рентгенофазовый анализ (РФА), термогравиметрический анализ (ТГА) с дифференциальной сканирующей калориметрией (ДСК). Проведены эксперименты по исследованию сорбционной способности полученных образцов Fe/Mg СДГ по отношению к хромат-ионам в нормальных условиях, а также при действии ультразвука, в т. ч. в сочетании с повышенным гидростатическим давлением. На фотоэлектрическом фотометре были получены и проанализированы данные c количественными значениями процесса сорбции. Данные, полученные в ходе комплексного анализа готового продукта, указывают на то, что синтезированный материал является Mg/Fe слоистым двойным гидроксидом. При проведении рентгенофазового анализа выявлено, что синтез СДГ с применением ультразвука и давления повышает степень кристалличности конечного продукта. Установлено, что сорбционные свойства СДГ, полученных традиционным способом, и СДГ, полученных под действием ультразвука и давления, отличаются. У Mg/Fe СДГ, синтезированных традиционным методом, сорбция хромата протекает лучше, чем у образцов, синтезированных при помощи ультразвуковой обработки в сочетании с повышенным гидростатическим давлением. Показано, что процесс сорбции исследованных образцов СДГ описывается разными математическими моделями.</p></trans-abstract><kwd-group xml:lang="en"><kwd>layered double hydroxides</kwd><kwd>Mg/Fe</kwd><kwd>ultrasonic synthesis</kwd><kwd>sorption properties</kwd><kwd>chromate ions</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слоистые двойные гидроксиды</kwd><kwd>Mg/Fe</kwd><kwd>ультразвуковой синтез</kwd><kwd>сорбционные свойства</kwd><kwd>хромат-анионы</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was supported by the Belarusian Republican Foundation for Fundamental Research (project No. H21RM-081).
