Investigation of Electrochemical Behavior of Co(II)-Disulfiram Complex at the Surface of Gold Electrode in Different Non-Aqueous Media

摘要

The redox properties of a Co(II)- Disulfiram complex has been examined using cyclic voltametry indifferent non-aqueous media such as dimethylsulfoxid (DMSO), dichlromethane(CH2Cl2) and mixedsolvents at the surface of gold , pelatin and glassy carbon electrodes. It has been found that, thiscompound exhibits one electron reduction peak with the EC mechanism. The charge transfercoefficients () and the diffusion coefficients (D values) for this compound in various solvents wereobtained on the basis of voltamograms. Effect of scan rate and dielectric constants of solvents on redoxbehavior of complex was investigated.
