STUDY OF METHODS FOR ACTIVATING BENTONITE CLAY FROM THE DARBAZA DEPOSIT

Abstract

In our country, the problem of water treatment remains urgent, and this is facilitated by the growth of external factors, which can include the increase in the number of industrial enterprises, agricultural development, urban growth and others. Objective. To solve the problem of wastewater treatment it is economically advantageous to create new sorbents, from the resources available in our country. Instrumental test methods were chosen for bentonite clay treatment under experimental conditions using scanning electron microscope (SEM) Jeol JSM-6490l V, FTIR spectrometer NEXUS E.S.P. (Thermo Scientific, USA), laser particle size analyser Analizette 22 MicroTec (Fritsch GmbH, Germany). According to the results of instrumental studies, the elemental and mineralogical composition of bentonite clay from Darbazi deposit was determined using scanning scanning electron microscope and FTIR spectrometer. The obtained sorbent on the basis of bentonite clay has a high sorption capacity and is recommended to be used in wastewater treatment of chemical industries. The obtained sorbent on the basis of bentonite clay from Darbazinsky deposit allows to purify wastewater of various productions containing ions of heavy metals up to 95%. The developed sorbent on the basis of bentonite clay has ecological and economic efficiency, connection with the use of local natural resources. Thus, it should be noted that for adsorptive treatment of wastewater from chemical industries with a high degree it is possible to use effective sorbents based on bentonite clays of Darbaza deposit. It should also be noted that the use of bentonite clays for water treatment by sorption process is an effective and affordable alternative to adsorbents, which show high adsorption capacity in relation to various compounds.
