Résumé:	This work focuses on the study of solid phase extraction of UO2 2+ using organic and inorganic materials. The characterization of these materials is made by FTIR spectroscopy, SEM scanning electron microscopy, X-ray diffraction DRX and BET. The optimal conditions for the extraction of UO2 2+ were determined by studying the influence of the parameters (pH, contact time, initial concentration of UO2 2+ ions, etc.). In order to evaluate the performance of the extractants used, we studied the thermodynamic, kinetic and diffusional aspect of uranyl sorption in the solid phases. Finally, a study by a fractional factorial plan was carried out to show the influence of each parameter dependently and independently.
