    • Abstract

       

      Binary complexes of zinc(II) with L-histidine/1,2-diaminopropane have been studied by using amalgam polarography. The characteristic of the composite polarograms show the irreversible nature of the electrode reaction process. The kinetic parameters such as standard rate constant,ks, and transfer coefficient α, have been determined by Randles’ method. Standard rate constants are of the order of 10−5 cm sec−1. There is evidence for the presence of Zn (histidine)3 species. Stability constants have also been determined.
