FIELD: environmental protection. ^ SUBSTANCE: invention concerns lands polluted with various organic and inorganic pollutants such as heavy metals, petroleum products an the like, and can be used for detoxification of various-type lands, e.g. in cases of man-caused pollution of lands, sewage disposal plant sediments etc. containing various types of pollutants in different concentrations. Method is implemented by adding glauconite-containing sorbent to land until specified concentration of polluting substance in the land is achieved. Prior to addition of sorbent, type of pollutant and its concentration K0 in polluted land sample is determined, after which concentrations K1, K2, K3, and K4 of polluting substance are measured for land-to-sorbent ratios 1:1, 1:2, 1:3, and 1:4, respectively, after which mass ms of the sorbent required to be mixed with land polluted with preliminarily determined pollutant in concentration K0 is determined to achieve desired concentration of pollutant K3 in terms of following equation: ms = mL*K1/[K3*(K0/K1 + K1/K2 + K2/K3 + K3/K4)4], where mL is mass of land polluted with preliminarily determined pollutant in concentration K0, and thereafter polluted land is moistened and calculated mass of sorbent is spread across the surface of polluted land while simultaneously being mixed with polluted land. ^ EFFECT: increased accuracy in determining mass of sorbent required and sufficient to achieve required norms of concentration of polluting substance in ground and so to reduce consumption of the sorbent. ^ 5 cl, 3 ex |
