Abstract

The scientific innovation of this study lies in the comparative analysis of humic acids extracted from the lignite of the Kumiskudyk and Kuznetsk deposits. Utilizing advanced techniques such as infrared spectroscopy, elemental analysis, and thermogravimetric analysis, a thorough investigation of the humic acids from these two distinct deposits was conducted. This approach enabled the identification of variations in their chemical composition, functional groups, thermal stability, and reactivity. The comparative analysis revealed unique characteristics of the humic acids, which are attributed to the distinct geological conditions of coal formation in each deposit. The study also uncovered differences in the quantities of carboxyl and hydroxyl groups, which directly influence their sorptive and complex-forming properties. These variations had not been previously studied in detail for these particular deposits. Furthermore, the research demonstrated that the humic acids from both deposits possess significant potential for applications in environmental science, agrochemistry, and wastewater treatment. However, their effectiveness may vary depending on the deposit and the composition of functional groups. These findings present new opportunities for the development of humic acid-based technologies and enhance understanding of the impact of geological factors on their chemical structure and properties.
