Abstract
FIELD: applied ecology. SUBSTANCE: polysaccharide-containing raw is boiled for 1-5 hr in the mixture consisting of ortho-phosphoric acid, dimethylformamide and urea. Mixture is washed to neutral pH value, dried, ground and mixed with filler at the ratio (1:1)-(1:99). Method is used for tobacco smoke component sorbent production for cigarette filters. EFFECT: improved method of sorbent preparing.
