Description

Within the frame of the investigation of interactions between uranium (VI) and hydrosoluble organic compounds for the prediction of the evolution of this ion in natural aquatic systems, and in order to obtain some missing data, the authors report a systematic experimental investigation of the interactions between U(VI) and humate in aqueous media. This study comprises a synthesis of humic acid, detection, identification and characterization of U(VI)-humate compounds with respect to different parameters (pH, U(VI) content and humate chemical composition), and the determination of conditional formation constants with respect to the pH. Significant results are commented
