Abstract
New complexone derivative of 8-hydroxyquinoline (quinolinol) was synthesized by the Mannich reaction from secondary and primary amines. Our synthesis was carried out either at room temperature or at reflux in good yields. Various analytical techniques ( 1 H & 13 C NMR, FTIR, Mass spectroscopy) were used to characterize our product. The use of this new extractant for the uptake and removal of UO 2 2+ in aqueous solution was investigated. Conditions for an effective sorption were optimized with respect to different experimental parameters in batch process. The total sorption capacity was 102 (mg.g -1 ) under optimum experimental conditions. Thermodynamic parameters showed the adsorption of an endothermic process and a spontaneous nature, respectively.
