The article contains the research results of properties of the sorbents produced from local bentonite clays with addition of oil sludge as a bloating component. To obtain a sorbent with high sorption properties using the local clays and oil sludge the thermal programmed hydrogen reduction and desorption was implemented. The modifying the local bentonite with acid and thermal processing showed, that the sorption properties are improved for account of cation exchange of the elements containing in the initial materials. Calculating Gibbs energy of formation reactions of sorbent minerals in the presence of organic compounds of the oil sludge permitted to conclude that the greatest thermodynamic probability is characteristic for the synthesis of sorbent minerals in the presence of C₆H₆, and the lowest one - in the presence of CH₃Cl. Judging by the results the activated clays containing the oil sludge can be applied for repeated purification of industrial waste water.
