Abstract
Carbon sorbents are obtained from Kuznetsk Basin coal by alkali activation. Their porous structure is established, and their sorptional activity in the extraction of organic pollutants and petroleum products is determined. The porous structure and sorptional activity of the sorbents are found to be correlated with the metamorphic stage of the initial coal. The most effective sorbents are produsced from subbituminous (D) and high volatile bituminous (G) coals. They prove effective in the removal of benzene and carbon tetrachloride from the gas phase; and in the removal of phenol and chloroform from aqueous solutions. In terms of the static capacity for phenol and chloroform, the coal derivatives match industrial sorbents.
