This paper deals with the potential use of hybrid magadiite composite as an alternative adsorbent for the removal of copper ions. Na-magadiite was synthesized by the hydrothermal method. The hybrid magadiite was prepared by using pyrazolone as an organic ligand via dry impregnation technique from Na-magadiite. The hybrid magadiite composite is used in the removal of copper ions in sulphate media. The presence of an organic molecule in hybride magadiite is verified by thermogravimetric analysis and infrared spectroscopy. The X-ray diffraction pattern illustrates the intercalation of the organic ligand into Na-magadiite interlayers and the preservation of the structure after intercalation. The scanning electron micrograph images of modified Na-magadiite show the expansion of the basal spacing resulted in a breakup of the spherical nodules and the concomitant parallel arrangement of the platelets. In batch experiments, the influence of reaction time, kinetics, pH and the initial concentration of copper(II) were investigated. In the case of modified Na-magadiite, the kinetic model of extraction adapted is pseudo-second order. The metallic cation was extracted at a very low pH 1.9, and the capacity obtained is 330 mmol/kg, the complex formed is of the CuL 2 type.
