METHOD OF REMOVING CRUDE OIL, PETROLEUM DERIVATIVES, AND OTHER HYDROCARBON POLLUTANTS FROM WATER AND/OR SURFACES, AND/OR SOLID SURFACES Russian patent published in 2001 - IPC

FIELD: oil pollution removal. SUBSTANCE: high-reactive carbon mixture is dispersed over water and/or solid surface, and/or within water bulk and then hydrocarbon-saturated carbon mixture is collected. Carbon mixture is prepared by chemically treating initial graphite-containing material (naturally occurred graphite or powdered graphite) with at least one halogen-containing compound of general formula MXO_n, where M is selected from H, NH₄, Na, and K; X is halogen; and n=1-4, followed by explosive decomposition of compounds initiated by photochemical, electrochemical, mechanical, thermochemical, sonochemical, or direct chemical action. Sorption material for water filter can be prepared in the same manner. EFFECT: enhanced water cleaning efficiency and enabled collection of other carbon chemical pollutants owing to carbon nanocrystals present in mixture and having high absorption capacity. 8 cl, 2 dwg, 2 tbl
