The study of sorption processes in the clay soils

UDK: УДК 624.131.41

V.V. Seredin, A.A. Kashevarova

montmorillonite and kaolinite clays were the object of the study. The aim of this work is to study the effect of pressure on the adsorption properties of clays. The methodology and results of the studies include: preparation of clay samples, compression under pressure, granulometric, X-ray diffraction, thermogravimetric analyzes, and experimental data processing. The study found that changes in the sorption activity of kaolinite and montmorillonite clays occur due to a change in the structure of clay particles, the crystal lattice of minerals, and the formation of additional active centers on their surfaces. When the clay is compressed, on the one hand, the processes of coarsening of clay particles proceed, which should lead to a decrease in sorption capacity. On the other hand, as the pressure increases, the structure of clay particles changes, which contributes to the formation of additional active centers on the surface of the crystal and colloid, which leads to an increase in the sorption capacity of clays and, as a consequence, to an increase in the loss of bound water masses.
