ABSTRACT
Within the framework of the concept of "green chemistry" and cyclic economy (economy of closed technological cycles) the extraction of chemical pollutants Cu2+, S2–, HS– - ions from wastewater of various industrial productions has been investigated. The research has been integrated into a single technological cycle of obtaining new carbon-sulfur-containing lubricants for special purposes. The loading and antifriction properties of the developed plastic lubricants has been investigated. It was established that the developed plastic lubricants in antifriction properties (ffr) are 1.25–1.45 times higher than the industrial lubricant Konstantin-1 and can be used in the work of friction units of various machines and mechanisms. Tribotechnical results of the developed plastic oils in the friction pair "steel-aluminum" are justified by the presence, first of all, in the composition of plastic oils of technical graphite brand LG-1, its modified forms of "pseudographite" and pyrocarbon, as well as sulfur-containing components CuSx and thiobenzaniline (TBA).
