DETERMINATION OF THE SUBSTANTIAL COMPOSITION AND SORPTION PROPERTIES OF CLAYS OF THE GERPEGEZHSKOYE DEPOSIT

The work of many industrial enterprises often leads to negative consequences for the environment: pollution by wastewater, which contains harmful substances, including heavy metals (HM), which in small quantities have a negative impact on human health and the ecological state of the biosphere as a whole. Today, about 80% of enterprises discharge their waste into natural waters. The relevance of the problem of wastewater pollution cannot be underestimated, since the deterioration of the hydrosphere ecosystem entails large-scale changes and deterioration of the state of all components of the environment, which can develop into a large-scale environmental disaster. The consequences can be various negative manifestations from depletion and loss of fauna and flora to fatal human diseases. In this regard, the issue of cleaning and neutralizing polluting components of wastewater by effective methods is important and topical. One of the quite effective methods of wastewater purification from nitrogen, phosphorus and heavy metal compounds is adsorption by natural mineral sorbents such as shungite, bentonite, etc. This article discusses the possibility of using bentonite from the Gerpegezh deposit in the Kabardino-Balkarian Republic to purify water to the MAC for copper (II) ion content.
