The effect of reagents on the production of highly nanocomposite bentonite sorbents using zol-gel technology

In this study, the analysis of the study of the effect of reagents upon receipt of cargo was highlighted—nanocomposite bentonite sorbents using Sol–gel technology and the results obtained were highlighted. The comparative surface surface was calculated at 77 K using a nitrogen adsorption isotherm. The size and pore size of the catalysts were determined from data on desorption and adsorption isotherms, respectively, at a relative pressure R/ro=0.99 in accordance with the BJH (Barette–Joyner–Halend) model. Bentonite in Navoi region of Navahor district is a light gray powder, odorless, practically insoluble in water and organic solvents, the pH value of the suspension is 7.1–8.7. The weak alkalinity of the suspension is explained by the presence of hydroxide soil and hydroxide metals in the clay. According to its adsorption properties, it is a combined meso–macromicrobial adsorbent, its specific surface area is 54.5 m2/g, the porosity volume is 0.065 cm3/g, the average porosity is 4.8 nm, the adsorption activity for blue methylene is 62.0 bentonite/g.
