956-958The electrochemical reduction of 4, 4'-dimethoxybenzophenone oxime (4, 4'-DMBPO) has been studied at the mercury electrode in different supporting electrolytes, in the pH range 2.0-12.0 including 0.1 M HCIO4 in methanol-water mixture by employing cyclic voltammetry, d.c. polarography and millicoulometry. Kinetic parameters such as diffusion coefficient, transfer coefficient and forward rate constant values has been evaluated
