“…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.

A significant number of sorbents used in the food industry are not reused due to the complexity of their regeneration and significant material costs. They are often stored on the territory of the enterprise or taken to landfills, usually without authorization. Today, it is important to study the regeneration and reuse of sorbents used in food production. It is promising to use sorbents previously used at the stage of water treatment or preparation of technological solutions and regenerated in wastewater treatment, in particular, in the same food production facilities and in other industries where wastewater contains organic substances. The article investigates the reuse of a spent sorbent mixture consisting of activated carbon and kieselguhr for the treatment of wastewater from dairy processing enterprises. The results of experimental studies of the dynamics of ion exchange adsorption of lactic acid and alanine by mixed sorbent and spent sorbent under periodic conditions are given. According to the results of the study, the difference in cleaning efficiency for the two options is insignificant and amounts to about 3%, which is within the experimental error. It is shown that the sorption of pollutant components of wastewater of milk processing enterprises by cheap sorbents, which include regenerated sorbents, is one of the most promising because of their high efficiency, low cost of treatment, and the possibility of further use of spent sorbents in agriculture.

Supported Ionic Liquid Catalysts for the Oxidation of S- and N-Containing Compounds—The Effect of Bronsted Sites and Heteropolyacid Concentration

et al. 2023

View full text Add to dashboard Cite

In this article, a series of effective catalysts based on betaine and sulfuric or phosphomolybdic acids was obtained. These compositions were characterized by various physicochemical methods and tested in the oxidation of sulfur- and nitrogenous-containing compounds by H2O2. An increase in the amount of heteropolyacid (HPA) leads to a non-linear change in acidity, and the degree of removal of sulfur-containing compounds correlates with the concentration of Bronsted acid sites on the surface. On the contrary, the degree of pyridine removal is determined primarily by the content of heteropolyacids in the catalyst.
