Abstract: A series of 3d-metals {Fe,Co, Ni, Cu and Zn) have been quantitatively separated from binary mixtures using suitable synergic combinations of bis(diphenylphosphinyl) ethane, with 8-hydroxyquinoline. There is synergic effect of 10-18% in the extraction of metals versus the use of 8-hydroxyquinoline alone. The formation of the extracted species is established using the slope analysis method. The extraction constants for the synergic species as well as stability constants are determined from the metal distribution data using linear regression analysis.
