The article investigated the sorption properties of natural sorbents (sawdust, wool, pinoges) used for cleaning soil from oil and oil products. The calculated values of the intensities for the selected sorbents in static and dynamic conditions. The results of determining the intensities in static conditions showed that the greatest value is achieved when using wool. Full saturation of the sorption materials oil for pinoges and sawdust occurs 15 minutes after the start of the experiment, for wool - over 60 minutes. It is shown that the values of the intensities of the sorption materials in static conditions is greater than the intensities in dynamic conditions. The quantitative characteristics of sorption of natural sorbents for cleanup of soils from oil testify to the effectiveness of pinoges to remove oil zagrazneniya – S – 59 % and allows us to offer pinoys as sorbent when cleaning oil-contaminated soils. The optimal time of sorption of oil for the selected adsorbents is in the range from 10 to 17 days.
