FIELD: chemistry.
SUBSTANCE: invention relates to environmental protection. Disclosed is a method of reducing soil contaminated with oil by mixing soil with calcium oxide and an acidic agent which forms calcium-insoluble compounds. Process of oil-containing soil recovery with extraction of hydrophilic soil is carried out by adding calcium oxide to the soil, and as acid agent - magnesium sulphate MgSO4 * 7H2O.
EFFECT: invention provides simplified process of oil-bearing soil recovery.
