Extraction of Cu(II) from hydrochloric acid media by Amberlite LA-1 hydrochloride dissolved in 1,2-dichloroethane.
The extraction of hydrogen chloride by a secondary amine (B), Amberlite LA-1, dissolved in 1,2-dichloroethane was studied by two-phase potentiometric titration. The results, treated by a general minimizing program, indicate dimerization: 2BHClright harpoon over left harpoonright harpoon over left harpoon(BCHl)(2). The equilibrium constant of this reaction was calculated. The extraction of cu(II) from 6M hydrochloric acid by Amberlite LA-1 hydrochloride (BCHl) dissolved in 1,2-dichloroethane, was also studied. The extraction of cu(II) can be explained as due to formation of two species, (BCHl)(2) CuCl(2) and (BCHl)(3) CuCl(2), in the organic phase. The formation constants of these species were calculated.
