FIELD: chemistry.
SUBSTANCE: surface is treated with a dispersed polymer-containing composite material, followed by regeneration or recycling of the spent product. The polymer used is a linear polymer with an unlimited degree of swelling in an oil product - latex of natural rubber or butadiene-styrene rubber, deposited on inert filler. The inert filler used is material with high specific surface area - vermiculite or oxidised graphite, obtained by foaming the starting component immediately before depositing the polymer on it. The filler is treated with the polymer at low pressure ranging from 0.9 atm to 1·10-4 atm. Sorbent is obtained in the apparatus directly at oil or oil product spill site.
EFFECT: high efficiency of the method of cleaning surfaces by increasing sorption capacity of the sorbent, reduced cost of transporting the sorbent.
