Abstract

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