Traitement, modification et caractérisation d’une argile algérienne

Abstract

In order to enhance clay’s qualities and increase the range of possible uses, this effort focuses on its modification, treatment, and characterization. As widely available natural resources, clays have inherent qualities that can be enhanced by different processes to suit particular requirements in a range of industries. This study began with the clay being treated chemically and physically in order to change its surface and structural characteristics. Acid activation, intercalation with different chemical agents, and particular heat treatments are used among the treatments. A number of characterization approaches were used to assess the efficacy of these adjustments. X-ray diffraction (XRD) for examining alterations in clay’s crystal structure. To determine the mineralogical composition, X-ray photoelectron spectroscopy is used. Use of Fourier transform infrared spectroscopy (FTIR) to monitor chemical changes and detect the presence of functional groups. In addition, clay's metal oxide content was investigated using UV-visible spectroscopy. The outcomes demonstrate how the treatments significantly altered the clay's physicochemical characteristics, particularly increasing its specific surface area and chemical reactivity. With these changes, modified clays can now be used in new industrial and environmental applications. As a result, this work highlights the significance of characterization methods and treatments in the creation of sophisticated clay materials that meet the demands of contemporary applications.
