CHEMISTRY AND CHEMICAL ENGINEERING
The purpose of the research is to study the adsorption properties and mineralogical structure of alkaline earth bentonites from the Navbakhor deposit, as well as to develop technological regimes for their acid activation for use as bleaching clay in the purification of vegetable oils. The authors, based on the structural structure of the studied bentonites, achieved an increase in adsorption capacity from 35 cm3/g to 100 cm3/g, by treating with hydrochloric and sulfuric acids with a concentration of 15-20% and in a bentonite:acid ratio of 1:2.5 at a temperature below 100°С. Nitrogen adsorption isotherms of activated …
