摘要: 在电极表面反应物浓度均匀的近似假设下, 得到了微圆盘电极上暂态可逆反应的一般解. 然后利用该一般解得到了微圆盘电极上耦合一级均相反应的可逆电极反应CE、EC、EC′和ECE 的稳态电流计算公式.

Abstract: In this work, reversible microdisk electrode reactions with coupled first-order homogeneous chemical reactions are discussed by means of the equivalence between the recombinated steady state diffusion equations and the Laplace transformed tran-sient diffusion equation of electrode reactions. First, general solution for transient diffusion equation of reversible microdisk electrode reactions is derived with “uni-form concentration” approach which is acceptable if D_O is close to D_R. And then, expressions for steady state current of CE, EC, EC' and ECE reactions at microdisk electrode are derived with the help of that general solution.
Key words: Microdisk electrode, Transient reversible electrode reaction, Electrode reaction with coupled homogeneous chemical reaction, Steady state electrochemical behaviour
