FIELD: compositions of solid sorbents. SUBSTANCE: invention relates to sorbents containing organic matters and can be used for treatment of water and soil surface, sewage and other substrates from oil, petroleum product and sewage. Sorbent has fibrous porous material as cellulose-containing matters and modified with polydiene compounds as 1,2-polydienes based on monomers with 4-5 carbon atoms in chain in syndiotactic form and having molecular mass 100 000-300 000 Da. Sorbent shows high sorption capacity, buoyancy and multiply regeneration. EFFECT: improved properties and quality of sorbent. 2 cl, 1 tbl
