В данной работе исследованы способы кислотной модификации бентонитовых глин месторождений Калжат и Орта Тентек, расположенных в Алматинской области Республики Казахстан, серной и азотной кислотой различных концентраций и определены эффективные концентрации. В данном исследовании были выбраны эффективные концентрации 20% H2SO4 и 10% HNO3, так как в ходе исследования бентонит модифицировали кислотами 10–98% H2SO4 и 10–65% HNO3. Среди этих концентраций по результатам различных исследований эффективными оказались кислоты 20% H2SO4 и 10% HNO3, эффективными же считаются концентрации, приведенные в данной работе. Полученные результаты изучены методами ИК-спектроскопии FTIR, рентгеновской флуоресценции, рентгеновской дифрактометрии и сканирующей электронной микроскопии. Модификация бентонита положительно влияет на раскрытие межслоевого пространства глины и улучшение ее свойств. После очистки и модификации бентонитовая глина может использоваться в сельском хозяйстве, производстве, медицине, а также в различных областях, таких как бурение, строительство и очистка воды.

In this work was investigated the methods of acid modification of bentonite clays from the Kalzhat and Orta Tentek deposits located in the Almaty region of Republic Kazakhstan with sulfuric and nitric acid in various concentrations and determined the effective concentration. In this study, the effective concentrations of 20% H2SO4 and 10% HNO3 were selected, because bentonite was modified with 10–98% H2SO4 and 10–65% HNO3 acids during the study. Among these concentrations, according to the results of various studies, 20% H2SO4 and 10% HNO3 acids were found to be effective, and the concentrations given in this work were considered effective. The obtained results were studied by the IR-spectroscopy FTIR, X-ray fluorescence, X-ray diffractometer and scanning electron microscope methods. Bentonite modification has a positive effect on opening the interlayer space of clay and improving its properties. After purification and modification, bentonite clay can be used in agriculture, manufacturing, medicine, and various fields such as drilling, construction and water purification.
