| Abstract | Abstract: The redox behaviour of Copper(II)-pentamethyldiethylenetriamine(pmdt) system has been studied in aqueous 0.2M NaClO4.6H2O supporting electrolyte at glassy carbon electrode(GCE) at various pH and pmdt concentration values by means of cyclic voltammetry. The cyclic voltammetric parameters are calculated. The first couple Cu showed a diffusion controlled, quasi-reversible, one electron charge transfer at GCE. The intensities of both cathodic and anodic peak current are increased with increasing scan rate consistent with Randles-Sevcik equation. The cyclic voltammograms indicated the presence of more than one complex specie in solution followed by complicated anodic response except for 1:100 Cu(II)-pmdt system at pH11.04. A linear behaviour of peak current versus square root of scan rate indicated that the electrochemical processes are diffusion controlled for 1:100 Cu(II)-pmdt at pH 7.10. |
