Abstract: The electrochemical oxidation of zinc O,O,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.

摘要: 采用循环伏安法和计时电量法等测试方法,以玻碳(GC)电极为工作电极,研究了O,O-二丁基二硫代磷酸锌(ZBPD)在含0.5 mol·L-1 LiClO4N,N-二甲基甲酰胺(DMF)水溶液(体积比9:1)中的电化学行为,并探讨了温度、扫描速率和底物浓度等因素对其电化学特性的影响。实验结果表明,ZBPD在GC电极表面的电氧化反应是受扩散控制的不可逆过程。估算了不同温度下ZBPD在DMF水溶液中的扩散系数D,进而求得其扩散活化能Ea约为29.52 kJ·mol-1
