The article deals with the studies on complex sorption treatment of industrial waste of various industries to obtain new C, S, N-containing plastic lubricants, which provide antiwear, antifriction, high load-bearing and heat-resistant properties. The conditions for obtaining diethylammonium salt from the obsolete pesticide Banvel D and its sorption on a mixed sorbent, which consist of activated carbon (AC) and kieselguhr (K), have been established. The conditions for obtaining potassium diethyldithiocarbamate and its adsorption on the surface of the mixed sorbent (AC + K), followed by treatment with copper(II) sulfate of corresponding bis-(diethyldithiocarbamato)copper(II) sorbed on a solid surface, have been examined. The obtained substances of general composition [sorbent (AC + K)]·[(C2H5)2NS(=S)S]2Cu were studied as active components of plastic lubricants, which provide their thickening, antiwear and antifriction properties. Industrial tribological research was carried out for friction pairs of four-row roller bearings of roller equipment used at private enterprise (PE) "Exim" (Kherson, Ukraine).
