“…Extraction of Cu 2+ -ions (83.2%) from industrial waters of electrochemical copper plating was performed using modified sulfide and hydrosulfide ions of a mixed sorbent (AC + K) [Khudoyavora O. et al 2020c]. Desulfurization of the sulfide-alkaline solutions from S 2-, HS --ions (96.6%) was carried out using a regenerated mixed sorbent (AC + K) [Khudoyarova O. et al 2020a;Khudoyarova O. et al 2020b]. The spent I-40A SN 300 industrial oil, which was used to obtain plastic oils, was regenerated with a mixed sorbent (AC + K) according to the method described in work [Khudoyarova O. et al 2020d].…”

Within the framework of the concept of "green chemistry" and cyclic economy (economy of closed technological cycles) the extraction of chemical pollutants Cu 2+ , S 2-, HS --ions from wastewater of various industrial productions was investigated. The research was integrated into a single technological cycle of obtaining new carbon-sulfurcontaining lubricants for special purposes. The loading and antifriction properties of the developed plastic lubricants were investigated. It was established that the antifriction properties (f fr ) of the developed plastic lubricants are 1.25-1.45 times higher those of the Konstantin-1 industrial lubricant Konstantin-1 and can be used in the work of friction units of various machines and mechanisms. The tribotechnical results of the developed plastic oils in the "steel-aluminum" friction pair are justified, first of all, by the presence, of technical graphite brand LG-1 plastic oils, its modified forms of "pseudographite" and pyrocarbon, as well as sulfur-containing components CuS x and thiobenzaniline (TBA) in the composition.

“…Regeneration of the spent mixed sorbent (AC+K) after the stage of purification of sugar syrup production of soft drinks was carried out according to the method described in works [6,7]. Methods of purification of water-sugar solutions are described in work [7], sulfide-alkaline solutions -in work [8][9][10][11], washing waters of the electrochemical copper plating process -in work [12]. Regeneration of waste industrial oils was carried out according to the method presented in work [13].…”

“…To increase the sorption capacity, it is popular to modify the sorption matrix using harmless and available reagents. Analysis of recent research and publications [9][10][11][12]13] has shown that the joint processing and disposal of waste from different industries allows you to remove valuable chemical compounds and significantly improve the ecological condition of the environment in their storage. The complex utilization of industrial waste studied today concerns, first of all, reagent extraction of metal cations from sewage of galvanic productions and other chemical wastes by their interaction and formation of waterinsoluble chemical compounds.…”

Complex processing of industrial waste of individual industries, including wastewater treatment, containing sulfur anions and cations of heavy metals, in order to obtain both purified water and finished industrial products is an urgent task for today. The possibility of efficient use of regenerated mixed sorbent (AC+K), containing activated carbon (AC) and diatomaceous earth (K), for wastewater treatment of certain technological processes of chemical (petrochemical) industry and galvanic industries has been shown. The sorbent with the removed contaminants was offered to be utilized as a part of plastic lubricants of special purpose. The technological process of complex sorption treatment of industrial wastewater from sulfide and copper (II) ions includes the following main stages: sorbent regeneration; purification of sulfide-alkaline solutions; purification of washing waters of galvanic productions; obtaining plastic oils. The basic technological scheme of the site of regeneration of the spent mixed sorbent (AC+K) and purification of water-sugar solutions from organic impurities was developed. The material balance of regeneration of the spent mixed sorbent was calculated. The basic technological scheme of the site of combined treatment of industrial wastewater from sulfide and copper (II) ions, regeneration of spent industrial oils with regenerated sorbent (AC+K) and production of plastic oils has been developed. It was shown that the technology of complex sorption wastewater treatment is based on the most common technological processes - heating, cooling, adsorption and filtration and does not require complex schemes of automatic process control, and chemical equipment is typical for chemical enterprises in Ukraine. The economic effect of production of special purpose plastic oils was calculated.
