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.

热化学活化高岭土和蒙脱土的吸附性能

摘要研究了热酸处理对高岭石吸附活性的影响。以前的出版物已经介绍了二氧化钛/高岭石材料的合成条件和性能的研究结果-一种具有家庭有机污染物被动降解功能的建筑材料填料;研究表明，与作为单独材料的高岭石和二氧化钛相比，复合材料在合成过程中的吸附结构特性显著增加。本文研究了模拟合成复合材料的热酸处理对二氧化钛潜在载体高岭石和蒙脱石吸附活性的影响。对高岭石的吸附活性有显著提高，表明了该处理方法对蒙脱土的低效率。

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.
