Study Of Textural, Sorption And Physicochemical Characteristics Of Kaolin And Bentonite

Abstract

The sorption, textural, and physicochemical characteristics of bentonite and kaolin are studied. To determine the relative surface of the samples, the Brunauer-Emmett-Teller method (BET) was used, and the Barret-Joyner-Helend method (BLC) was used to determine the volume and size of pores. As a result of the research, a relationship was established between the volume of adsorbed gas and the relative pressure and pore radius. It has been established that at P/P₀ = 0-0.05 in the mesopores monomolecular adsorption is observed, at P/P₀ = 0.05 simultaneously mono- and multimolecular adsorption, at P/P₀ = 0.05-0.4 there is a polymolecular adsorption
