      <abstract xml:lang="ru">
        <p>Рассмотрены гетерогенные системы, включающие природные углеродные матрицы в твердой фазе и водные растворы низкомолекулярных органических соединений с положительными и отрицательными отклонениями от идеальности в жидкой фазе. Дана техническая характеристика рассматриваемых супрамолекулярных ансамблей на основе бурого угля месторождения Кара-Кече (Кыргызстан), выделенных из него гуминовых кислот и гумина. При помощи ИК-Фурье спектроскопии проведен функциональный анализ образцов. Исследована морфология поверхности рассматриваемых углеродных матриц, в различных точках которой установлен локальный микроэлементный состав. Проведен рентгенофазовый анализ бурого угля Кара-Кече, выделенных из него гуминовых кислот и гумина. Изучена изотермическая адсорбция биполярных молекул глицина и мочевины, нейтральной D-глюкозы из водных растворов на твердых углеродных сорбентах. Сделано предположение об адсорбции низкомолекулярных органических соединений из водных растворов на гумине и угле Кара-Кече в неровностях и порах углеродной матрицы сорбентов, для гуминовых кислот – на поверхностных реакционных центрах. В силу развитой поровой структуры, устойчивости в кислотах и щелочах гумин угля Кара-Кече рекомендован для очистки промышленных сточных вод от низкомолекулярных органических экотоксикантов.</p>

        <p>Heterogeneous systems including natural carbon matrices in the solid phase and aqueous solutions of low molecular weight organic compounds with positive and negative variations from ideality in the liquid phase are considered. The technical characterization of the considered supramolecular ensembles on the basis of brown coal of the Kara-Keche deposit (Kyrgyzstan), humic acids and humine extracted from it is given. Functional analysis of the samples was carried out using FTIR spectroscopy. The morphology of the surface of the considered carbon matrices has been investigated, in different points of which the local microelement composition has been established. An X-ray phase analysis of Kara-Keche brown coal and humic acids and humine extracted from it was carried out. The isothermal adsorption of bipolar molecules of glycine and urea, neutral D-glucose from aqueous solutions on solid carbon sorbents has been studied. An assumption has been made about the adsorption of low molecular weight organic compounds from aqueous solutions on humine and Kara-Keche coal in irregularities and pores of the carbon matrix of sorbents, for humic acids – on surface reaction centers. Due to its developed pore structure and resistance to acids and alkalis, humine from Kara-Keche coal is recommended for the purification of industrial wastewater from low molecular weight organic ecotoxicants.</p>
