| In this paper, a new and simple extraction method has been developed for preconcentration and optimization of Bi (III) in the aqueous phase by cloud point extraction. This method is based on the complex metric reaction of Bi (III) with dithizone as a chelating agent in the presence of sodium dodecyl sulfate (SDS) which was used also as an extracting agent at room temperature. Besides, central composite design (CCD) based response surface method (RSM) was applied for the optimization of main experimental parameters such as pH of solutions, the concentration of the chelating agent, surfactant, and salt. The interference effect of some anions and cations was also tested. Finally, the method was successfully applied to the simultaneous determination of Bi (Ш) in bismuth subcitrarte tablet. |
