Abstract

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.
