Synthèse des Composites à base d’argile et application à la décontamination des colorants.

Abstract

This study was devoted to the development of a series of bio-composite materials based on raw bentonite by adopting a simple method. The characterization of these composites was carried out by infrared spectroscopy, XRF, DRX and ATG. The composite materials obtained are then applied to remove the dye (anionic and cationic), in particular methylene blue and methyl red in aqueous solution. The parameters governing the adsorption phenomenon such as concentration, pH or contact time have been carefully analyzed. Elaborated materials can be used effectively to remove dyes.
