摘要： 运用积分变换的方法推导了超微带电极上同时受扩散、化学反应、电化学反应动力学控制的伏安关系,得到了前行化学反应、平行化学反应和后行化学反应的准可逆伏安方程,并列出了计算所得的典型伏安曲线。

关键词: 超微带电极, 单一化学反应, 准可逆电荷转移

Abstract: The theory of electrochemical processes controlled by diffusion,chemical reaction and electrode reaction occurring at ultramicroband electrodes are investigated by means of integral transformations.Multidimensional integral equations related to the Eqcirr,Eqcirr and crev Eq coupled with quasi-reversible charge transfer are obtained,the results we obtained as follows:For EqCirr process:   where f(t,x) is the dimensionless electroactive species flux on electrode surface.The voltammogram can be calculated by numerical method,and the typical i-E curves are shown in this paper.

Key words: Ultramicroband electrode, Homogeneous chemical reaction, Quasi-reversible charge transfer
