Investigation of Catalytic Effect Nitrite on Electrochemical Reduction of Cobalt Dimethylglyoxime Complex by Polarographic and Voltammetric Techniques

摘要

The voltammetric and polarographic behaviour of Cobalt Dimethylglyoxime (Co-DMG) complex on audhanging mercury drop electrode (HMDE) and static mercury drop electrode (SMDE) has been studiedudby several techniques including Square wave voltammetry (SWV), Differential pulse polarographyud(DPP) and stripping techniques. Polarographic and voltammetric curves recorded at HMDE andudSMDE provide information about electrode reaction mechanism. Catalytic effect of nitrite on theudelectrochemical reduction mechanism of the complex have been explained.
