Abstract
The present paper investigated the electrochemical behaviour of Schiff base and its zinc complex at a working electrode by cyclic voltammetry technique. In the phosphate and Britton-Robinson buffers, the electrochemical study of Schiff base was performed within various pH values 5-9. Cyclic voltammograms of the examined Schiff base exhibited irreversible and diffusion controlled waves at different sweep rates, which is associated with the two electron reduction process of azomethine group. The symmetry transfer coefficient (αn), the diffusion coefficient (D01/2) and rate constant (k°f,h) of the reactant species were calculated. Cyclic voltammetric study of zinc complex showed one electron diffusion controlled, quasi-reversible peaks at 50-250 mV/s sweep rates. Antimicrobial study of zinc complex showed that zinc complex found to be more potent than uncoordinated Schiff base.
