عنوان انگلیسی Kinetic and Thermodynamic Evaluation of the Uranium (VI) Stripping from Alamine-336 in the Presence of Iron (III)
چکیده انگلیسی مقاله An economic process was developed via the batch scale for the uranium (VI) stripping in the presence of iron (III) from loaded alamine-336 by ammonium carbonate solution. The optimum conditions were assessed for the uranium (VI) stripping using the central composite design method, which is a subset of response surface methodology. The R-squared, U (VI), and Fe (III) stripping percentages with a value of equal 0.989, 72.61%, and 0.1% were obtained, respectively in the optimum conditions of the U (VI) and Fe (III) stripping from loaded alamine-336. The optimum stripping conditions led to the obtaining of the ammonium carbonate concentration equal to 0.64 mol/L, the phase ratio of 0.8 (O/A), the temperature of 53 , the contact time of 2510 seconds, and the shaking speed of 1100 rpm. Moreover, the stripping kinetics, equilibrium constant, and thermodynamic data were determined to describe the nature of the U (VI) and Fe (III) stripping from loaded alamine-336 by the ammonium carbonate solution. The temperature-dependent data showed that the U (VI) stripping was an endothermic process.
