ARTICLE ANNOTATION

quote
The article discusses the creation of a new adsorbent for wastewater treatment of leather enterprises. It is shown on the example of leather enterprises that solving the problem of economical use of water, reducing the amount of wastewater, reducing their pollution is currently one of the most important in Uzbekistan. In the total volume of water consumed at present, the proportion of water consumed repeatedly for leather dressing is practically zero. In the manufacture of leather, more than 150 names of various chemicals of both organic and inorganic origin are used.For clay minerals, as well as for zeolites, along with ion exchange, physical and molecular sorption are characteristic.Sorbability, as well as hydrophilicity, depends on the structure of the compounds included in its composition of functional groups. It was established experimentally that native clay is capable of absorbing up to 84% of copper (II) ions, and the possibility of modifying bentonite clay can increase the efficiency of wastewater treatment from 83-86 to 90-95%. A linearized sorption isotherm is presented. The parameters of the adsorption layers of surfactants during adsorption on various clays are given. It was found that an increase in the sorption capacity during the processing of natural clays by microwave radiation is associated with the partial destruction of aquacomplexes that communicate between the packets, which contributes to a better penetration of the sorbed substances to the centers of concentration of negative charges.
