Study of the sorption characteristics of activated carbon material

The development of new highly efficient sorption materials for the separation of various liquid or gaseous media is an important area of modern research that is in demand in a number of industries. The paper presents the results of studies conducted to determine the sorption capacity of a highly porous carbon material obtained by implementing two activation options - high-temperature alkaline activation and activation with additional processing of the material with steam. As a result, the obtained activated highly porous carbon material had a specific surface area of 2500-2700 m2/g and a pore volume of more than 1.3 cm3/g. A high sorption activity was established with respect to synthetic dyes - methylene blue and methylene yellow. Comparison with analogue materials showed that the resulting carbon material significantly exceeds them in sorption capacity and is a promising absorber of pollutants from aqueous solutions, which demonstrates the possibility of its use for solving environmental problems.
