Abstract

The electrochemical oxidation of zinc O

O'-tetrabutyl bis(phosphorodithioate)(ZBPD)on glassy carbon electrode in DMF-H2O solution was studied by cyclic voltammetry and chronocoulometry. The influences of temperature

scan rate and ZBPD concentration on the electrochemical characteristics of ZBPD were also investigated.The results showed that the electrochemical oxidation of ZBPD in DMF-H2O solution was an irreversible process with one electron transferred

which was controlled by diffusion.Charge-time curve for the electrochemical oxidation of ZBPD in DMF-H2O solution at various temperatures were obtained by chronocoulometry.In terms of the Cottrell equation

diffusion coefficient was estimated for each temperature

and it increased with temperature.According to the Arrhenius equation

the activation energy of diffusion of ZBPD in DMF-H2O solution was calculated to be 29.52 kJ·mol-1.
