The research was carried in order to study the effectiveness of using alumino-silicate vermiculite mineral of various modifications as a sorbent for the purification of environment from oil products. Thermally activated vermiculite with hydrophilic properties can be used to clean oil-contaminated areas, prevent hydrocarbon migration and improve the structural condition of polluted soils. Immobilization on the sorbent of bacteria cells-oil destructors of the genus Pseudomonas increases its efficiency and contributes to a more rapid recovery of the polluted environment. The treatment of thermally activated vermiculite with a water-repellent spirit makes it possible to obtain a sorbent with high water resistance properties. The use of a water-repellent sorbent in the purification of water from diesel fuel makes allows achieving a high degree of purification-up to 99.8%. Such a sorbent can be used for localization and collection of oil and petroleum products in coastal waters, as well as for cleaning oil-contaminated wastewater. The sorbent used in the cleaning process can be restored and reused.
