Physicochemical Characterization of Intercalated Kaolinite

EasyChair Preprint 6213

Abstract

This work aims in particular the characterization of a hydrothermal clay of eastern Algeria, intercalated by cationic surfactant (DTAC). The intercalation is intended to space the sheets (the interlayer space) of the material as far as possible and to widen the advantages of its basal distances, as well as to increase its hydrophobicity. The preliminary study of this material was made using several methods: X-ray diffraction characterization, scanning electron microscope analysis, ATG, ATD; chemical analysis and determination of specific surface area by BET analysis. The results obtained showed that this clay is of kaolinite type. The textural analysis of the intercalated kaolinite was made by the B.E.T method and the specific surface area of ​​the intercalated clay is thus determined. This characterization aims more particularly at the study of the structural and textural properties, which could allow an exploitation of this material in different fields of specific applications, given its availability and its great economic interest.
