FIELD: chemistry.
SUBSTANCE: group of inventions relates to compositions of hard porous sorbents and can be used for collection of oil, oil products and organic solvents from various surfaces, including water, soil, etc. Sorbent contains hard porous carrier and organic modifier. In the first variant, direct or active dye based on porphyrins and phthalocyanins are used as organic modifier. In the second variant, vat dye is used as organic modifier. In the third variant, sulphur dye is used as organic modifier. Proposed sorbent in all variants ensures improvement of sorbent sorption properties due to modification of carrier surface.
EFFECT: improved sorption properties of sorbent.
