FIELD: chemistry.
SUBSTANCE: invention relates to methods of making an adsorbent for purifying water contaminated with oil and oil products, and can be used in treating waste water from thermal power plants and removing oil and oil product spills from the surface of water. The method of making a hydrophobic adsorbent involves modifying sludge from thermal power plant clarification tanks with grain diameter of 0.01-1.4 mm, followed by heat treatment at temperature of 140-160°C for 8-10 minutes. Modification is carried out with 100% organosilicon liquid Silor, with volume ratio of the liquid phase to the solid phase of (0.2-0.3):1.
EFFECT: invention increases efficiency of purifying natural water and waste water from oil and oil products and widens the range of oil sorbents.
