Abstract

The paper deals with the optimization of uranium back extraction from the Alamine-336 loaded by synthetic solution (synthetic LOS) and Bandarabbas leach liquor (real LOS) by means of Stripping process method. In this regard, the impact of two essential parameters including the reagent concentration and phase ratio (O: A) for Stripping of alkaline agent containing sodium hydroxide (NaOH) and sodium carbonate (Na2CO3) togather with the pH for sodium chloride (NaCl) were investigated. To study these effects, a central composite design (CCD) under the response surface methodology (RSM) was employed. Based on the design of the experiments, the second-order regression model has been constructed to evaluate the optimzation of the Stripping efficiency of uranium from Alamine-336. The optimum conditions for these Stripping agents have been determined as NaCl (0. 6 mol L-1) with the ratios of O: A (1. 41) and pH (3. 1) NaOH (1. 33 mol L-1) with the ratio of O: A (1. 26) and Na2O3 (0. 72 mol L-1) with the ratio of O: A (1. 16). Under these optimal conditions, the Stripping efficiency values up to %31, %45 and %54 were obtained for NaCl, NaOH, and Na2CO3 cases, respectively.
