Abstract

The paper studies the effect of mechanochemical activation on the composition, properties and structure of shungite rocks of the Koksu deposit. The use of nanostructured shungite powder in sorbents can lead to an improvement in their sorption properties. As a result of mechanochemical activation in the samples of shungite rocks of carbonate and shale origin, the mass fraction of carbon decreases, and the mass fraction of silicon increases. The composition of the rocks also increases the content of oxygen, aluminum and iron, which contributes to the improvement of the sorption properties of shungite. Mechanochemical activation led to an increase in the specific surface area, specific volume, and pore size of the samples. As a result of the mechanochemical activation of shungite samples, the surface structure of the material changes, and carbon materials with a more developed surface structure and increased porosity are obtained.
