Abstract

The complexation reaction of Cd2+ and Pb2+ ions with 1, 10-Phenanthroline (Phen), 2, 2' Bipyridine (Bipy) and 8-hydroxyquinoline (Oxine) were studied in solvents of water, methanol and DMF by means of differential pulse polarographic (DPP) technique. This method is based on the comparison between polarograms of metal ion and metal-ligand complexes. The negative shift of the reduction of complex, in comparison with metal ions, is the basis for study of the stoichiometry and stability constant of complex, using the Lingane equation. It is seen from the final results that the stability of the heavy metal ions with Phen, Bipy and Oxine varies in order Cd2+> Pb2+. In the case of all metal ions, the stabilities of the resulting complexes increased in the order Phen > Bipy > Oxine. There is also an inverse relationship between the stabilities of complexes and solvating ability of the solvents. Finally, determination of trace Analysis of such metals in wastewater solution is discussed.
