FIELD: purification of aqueous medium against petroleum, oil and other hydrocarbons by using of powder ferromagnetic sorbents. SUBSTANCE: powder comprises ferromagnetic, carbon and hydrogen, it has spherical particles being 0.15-0.5 μm in size. Mass ratio of carbon and hydrogen in it is 30-60. Sorbent comprises, mass %: ferromagnetic, 60.0-80.0; carbon, 8.8-38.8; hydrogen, 0.2-1.2. With sorbent it is possible to extract up to 95 % of petroleum of emulsions and to collect 95-100 % of petroleum from the surface of water. Due to low content of sorbent in thus collected mixture said mixture may be used for production of benzine fraction of petroleum and other petroleum fractions. EFFECT: improved purification of aqueous medium against petroleum, oil and other hydrocarbons.
