Bentonite adsorbents from clay minerals are now used in many industries. At present, bentonites are one of the most important adsorbents in the food industry for the purification of various gas fields and other organic compounds. In addition, local bentonites are widely used in oil drilling. However, to date, there are few data on the presence of certain active centers or their dependence on the properties of the surface structure. Since the catalytic activity of clay minerals is not scientifically substantiated, it is necessary to produce highly efficient adsorbents that meet international requirements. Fundamental research is constantly needed to study adsorption processes in bentonites at the level of molecular systems. The adsorption mechanism on the bentonite surface has been described in complete thermodynamic processes using the volumetric method in a highly sensitive microcalorimetric adsorption device.
