FIELD: chemistry.
SUBSTANCE: cellulose-containing wastes of the tobacco-caporal production of plant origin in the form of tobacco dust is mixed with an aqueous suspension of bentonite clay having a ratio (pts wt): bentonite clay: water is 3:5. A plastic mass having a component ratio (wt %): tobacco dust - 50-70, clay suspension - 30-50, is granulated. The granules are chemically treated in a solution of sulfuric acid and heat treated at a temperature of 300-750°C.
EFFECT: obtaining an effective sorbent suitable for complex wastewater treatment from a wide range of pollutants.
