The invention relates to the field of environmental protection and can be used to remove liquid hydrocarbons from bodies of water and solid surfaces. A method of producing a liquid hydrocarbon sorbent consists in that a collagen reticular plastic foam is placed in an aqueous solution of a plasticizer containing hydroxyl groups, held at 10-50°C for 10-30 minutes, squeezed out, and dried, and a finished sorbent is obtained with a plasticizer content of from 10 to 50 wt%. The resulting liquid hydrocarbon sorbent is a collagen reticular plastic foam plasticized by a substance containing hydroxyl groups. Moreover, said plastic foam may be plasticized with glycerin, or ethylene glycol or polyethylene glycol. The sorbent has high strength, high hydrocarbon capacity and a high rate of hydrocarbon sorption. |
