Study of complex formation constants of uranyl and cadmium metal ions with primaquine by using differential pulse voltammetry

Tanaji N.Bansode

The electrochemical behavior of complexes of primaquine diphosphate with U (IV) and Cd (II) were studied. It was observed that primaquine forms 1:2 complexeswithU(IV) and Cd (II) buffer at pH4.0 by usingDifferential pulse Voltammetry (DPP). The stability constants of primaquine-metal complexes were evaluated with the DeFord-Hume procedure at different ligand concentrations using DPP. The logarithm values of stability constants of Uranyl and lead complexes are 11.74 and 8.17, respectively
