Мировой спрос на недорогие, доступные, безопасные материалы растет, в том числе в сфере очистки промышленных и сельскохозяйственных газовых выбросов от сероводорода. В статье представлен анализ литературных данных о природных глинах, активном иле и других материалах и способах их использования для адсорбции сероводорода. Приведены данные о составах активного ила, глин и известняковых пород, исследования которых проведены на инфракрасном спектрофотометре. Неорганическая составляющая активного ила включает в себя оксид железа, соединения алюминия, кальция, магния, силикаты. Горная известковая порода состоит из карбонатов, оксида железа, силикатов, при прокаливании при высоких температурах образует преимущественно оксид кальция. Различные глины содержат алюмосиликаты, оксиды железа, меди, кобальта, марганца. За счет содержания оксидов металлов природные материалы имеют механизм хемосорбции, а за счет содержания соединений алюминия и кремния обладают физическим механизмом сорбции. Разработаны 17 составов композиционных материалов из природных минералов и изучено их содержание серы. Также было проведено исследование поглощающей способности активного ила в жидком состоянии. Показано, что все природные материалы обладают высоким потенциалом для использования в качестве адсорбентов при минимальной подготовке (обезвоживании, прокаливании). Композиции, не содержащие дорогостоящих добавок, состоящие в основном из обожженной известняковой породы и глин, показали сероемкость от 10 до 40 %.</p></abstract><trans-abstract xml:lang="en"><p>Adsorption materials based on natural minerals are considered in the world literature as inexpensive hydrogen sulfide adsorbents capable of completely replacing commercial products such as synthetic zeolites. The global demand for inexpensive, accessible, safe materials is growing, including in the field of cleaning industrial and agricultural gas emissions from hydrogen sulfide. The article presents an analysis of literary data on natural clays, activated sludge and other materials and methods of their use for hydrogen sulfide adsorption. Data on the composition of activated sludge, clays and limestone rocks are provided. The composition studies were carried out on an infrared spectrophotometer. The inorganic component of activated sludge includes iron oxide, aluminum, calcium, magnesium compounds, and silicates. Limestone consists of carbonates, iron oxide, silicates, and when calcined at high temperatures, it mainly forms calcium oxide. Various clays contain aluminosilicates, iron oxides, copper, cobalt, and manganese. Due to the content of metal oxides, natural materials have a chemisorption mechanism, and due to the content of aluminum and silicon compounds, they have a physical sorption mechanism. 17 compositions of composite materials from natural minerals were developed and their sulfur content was studied. A study was also conducted on the absorption capacity of activated sludge in a liquid state. It was shown that all natural materials have a high potential for use as adsorbents with minimal preparation (dehydration, calcination). Compositions that do not contain expensive additives, consisting mainly of сalcined limestone rock and clays, showed sulfur capacity from 10 to 40 %.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сероводород</kwd><kwd>адсорбенты</kwd><kwd>глина</kwd><kwd>бентонит</kwd><kwd>известняк</kwd><kwd>очистка газа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrogen sulfide</kwd><kwd>adsorbents</kwd><kwd>clay</kwd><kwd>bentonite</kwd><kwd>limestone</kwd><kwd>gas purification</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by a grant provided by the Academy of Sciences of the Republic of Tatarstan for conducting fundamental and applied scientific research in scientific and educational institutions, enterprises, and organizations of the real sector of the economy of the Republic of Tatarstan (No 15/2024-FIP of 24.12.2024. “Block for the preparation of gas emissions from petrochemical enterprises for energy use”).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Alguacil F.
