FIELD: ecology.
SUBSTANCE: humic-mineral reagent is prepared by mixing humified organic raw materials with the solution of hydroxide of alkaline or alkaline-earth metals, followed by extraction. The extraction of humic substances is carried out at 165-220°C and pressure of 1.8-2.5 MPa while simultaneous supplying air at a rate not exceeding 5 litres per minute for 10 kg of raw material for no longer than 3 hours. The resulting reagent comprises humic acids and/or their salts, a mixture of mineral components, comprising ferric oxide, sodium oxide, magnesium oxide, aluminium oxide, calcium oxide, and less than 1.5 wt % impurities.
EFFECT: invention enables to obtain new environmentally and economically effective humic-mineral agent with a high yield of organic wastes, the use of which provides effective cleaning of contaminated soils, and to accelerate remediation processes.
