   <abstract xml:lang="ru">
    <p>Тяжелые металлы, такие как железо, являются распространенным компонентом природных и сточных вод. Результаты мониторинговых исследований свидетельствуют о загрязнении подземных вод железом до 30 ПДК вблизи разработок рудных месторождений и карьеров, поскольку этот элемент входит в состав горных пород и почв и вымывается при контакте с водой. Наиболее эффективным и экономически целесообразным методом доочистки природных и сточных вод от ионов железа является адсорбция. Выбор типа адсорбента играет существенную роль в эффективности процесса адсорбции. Цель работы заключалась в выборе наиболее подходящего сорбционного материала для элиминации воды от ионов железа и установлении закономерностей и механизма процесса адсорбции на сорбентах с различными свойствами для создания экологически безопасных и эффективных технологий адсорбционной очистки.&#13;
Объектами исследования являлись несколько типов сорбентов, таких как сорбент из углеродистого материала марки СКД-515, сорбционные материалы минерального происхождения АС на основе алюмосиликата и сорбент ОДМ-2Ф на основе осадочной горной породы опоки. Пористую структуру материалов изучали методом порометрии, получение изображений поверхности образца – методом сканирующей электронной микроскопии. Провели исследование равновесия, кинетики и динамики процесса адсорбции железа на сорбентах различной природы.&#13;
Для расчета основных адсорбционных параметров использовали уравнения Фрейндлиха и Ленгмюра. Рассчитанные величины энергии Гиббса по уравнению Ленгмюра составили 11,93–20,66 кДж/моль, что свидетельствует о физическом характере процесса адсорбции. Исследование свойств сорбентов в статических условиях свидетельствует об их высокой адсорбционной ёмкости по отношению к железу и позволяет расположить их по эффективности извлечения в ряд АС &gt; СКД-515 &gt; ОДМ-2Ф, что связано с различной структурой материалов. Адсорбция железа протекает в микропорах для СКД-515 и мезопорах для сорбентов АС и ОДМ-2Ф. Изучение кинетики извлечения ионов железа позволило сделать вывод о том, что процесс адсорбции лимитируется внешним массопереносом. &#13;
Полученные результаты дают новое понимание механизма адсорбции ионов железа на сорбционных материалах различной структуры, подкрепленное изображениями, которые получили методом сканирующей электронной микроскопии. В динамических условиях исследовали влияние таких параметров, как начальная концентрация, скорость потока и высота слоя загрузки на время непрерывной работы адсорбционной колонны. Система показала эффективную работу, достигнув 99,0 % извлечения ионов Fe3+ при следующих условиях: скорость потока 1 л/мин, высота слоя загрузки колонны 0,15 м, диаметр колонны 0,05 м, начальная концентрация 0,5 мг/л (5 ПДК). Также работу колоны тестировали при начальной концентрации ионов железа 50 ПДК, моделируя очистку сточных вод промышленных предприятий. Комплексное исследование адсорбции ионов Fe3+ из сточных вод показало эффективную очистку при использовании сорбента марки АС.</p>

    <p>Natural waters and wastewaters often contain heavy metals, e.g., iron. Iron ore mining contaminates groundwater with iron up to 30 maximal permissible concentrations (MPC) as this element gets washed out from rock and soil. Adsorption is the most effective and economically feasible method of additional purification of natural and wastewater from iron. Its efficiency depends on the type of adsorbent. The research objective was to select the most efficient sorption material to eliminate water from iron, as well as to establish the adsorption patterns for different sorbents, thus creating sustainable and effective purification.&#13;
The study featured carbonaceous sorbent of the SKD-515 grade, mineral sorption materials with aluminosilicate of the AC grade, and silicate-based sorbent of the ODM-2F grade. The porous structure was studied by porometry methods while the surface image was obtained using scanning electron microscopy. Other indicators included equilibrium, kinetics, and dynamics of iron adsorption by various sorbents. &#13;
The Freundlich and Langmuir equations made it possible to calculate the key adsorption parameters. The Gibbs energy values were obtained from the Langmuir equation and equaled 11.93–20.66 kJ/mol, which indicated the physical nature of the adsorption process. Under static conditions, the sorbents demonstrated a high adsorption capacity with respect to iron, depending on the structure, and could be arranged as AC &gt; SKD-515 &gt; ODM-2F. In SKD-515, iron adsorption occurred in micropores; in AC and ODM-2F, it took place in mesopores. The kinetics of iron extraction showed that the adsorption process was limited by external mass transfer.&#13;
The research provided a new understanding of iron adsorption by materials of various structures. The conclusions were supported by scanning electron microscopy images. Initial concentration, flow velocity, and loading layer height were studied in dynamics, i.e., during continuous operation of the adsorption column. The system proved extremely effective and reached 99.0% Fe3+ extraction under the following conditions: flow rate = 1 L/min, loading column height = 0.15 m, column diameter = 0.05 m, initial concentration = 0.5 mg/L (5 MPC). The column performance was tested at an initial concentration of iron ions of 50 MPC, which simulated the wastewater treatment at industrial enterprises. This comprehensive study of iron adsorption from wastewater proved the efficiency of the mineral sorption materials with aluminosilicate of AC grade.</p>
