FIELD: removal of petroleum and petroleum products from water surface and from sewage water. SUBSTANCE: method involves sorbing above-mentioned products by hull of rice grains carbonized at 450-600 C and atmospheric pressure or at 500-700 C and pressure of 200-759 mm of mercury column or in nitrogen medium at 550-650 C and atmospheric pressure. Recovery of sorbent is effectuated by hydrocarbon solvent (benzine, rekosine), organic solvent (methylated spirit) or their mixture. EFFECT: increased efficiency in removal of contaminants. 2 cl
