Structural Features and Sorption Properties of Mesoporous Carbon Material Prepared from Natural Shungite

— A novel carbon sorbent has been prepared from natural shungite by removing noncarbon components. We have studied sorption properties of this material for heavy metal ions and methylene blue, a cationic dye. The results demonstrate that the sorbent has high adsorption capacity for heavy metal ions (247 mg/g) and cationic dyes (120 mg/g) and can be used to remove them from aqueous solutions.
