Adsorption Properties of Kaolinite and Montmorillonite Activated by Thermochemical Treatment
Abstract
The article presents the results of a study of the effect of thermal acid treatment of kaolinite on increasing its adsorption activity. Previous publications have presented the results of a study of the synthesis conditions and properties of the TiO2/kaolinite material—a filler of building materials with the function of passive degradation of household organic pollutants; the studies showed a significant increase in the adsorption–structural characteristics of the composite during synthesis compared to kaolinite and titanium dioxide as separate materials. The current article is devoted to study of changes in the sorption activity of potential carriers of titanium dioxide—kaolinite and montmorillonite—as a result of thermal acid treatment, which simulates the synthesis of a composite. A significant increase in the adsorption activity of kaolinite is obtained and the inefficiency of this treatment method for montmorillonite is shown.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
