FIELD: tobacco industry.
SUBSTANCE: invention relates to coal filters of smoking products. Proposed is a method for production of a filter for tobacco smoke filtering that involves production of mesoporous coal by way of preliminary treatment of the source material with alkali solution, activation and introduction of produced mesoporous coal into the smoking product filter. The source material is a coal precursor representing a lignocellulosic material. According to the method, preliminarily treated material is not activated in the presence of alkali.
EFFECT: proposed is a method for production of a filter for tobacco smoke filtering.
