Abstract: The paper is devoted to the study of the sorption properties of residual coal formed after hydrocavitation treatment of brown coal of the Olexandria deposit. The study aims to investigate the possibility of more efficient usage of brown coal processing products that have undergone cavitation treatment. Hydrocavitation of earthy brown coal provides complete and fast extraction of humus acids during extraction with the sodium hydroxide solution. At the same time, the residual coal is pulverized to the size of 10-20 µm. It was shown that the residual carbon has a high sorption capacity (the degree of extraction of methylene blue from the solution is more than 95%).
