摘要
经过严格的数学推导及合理的数学近似,提出了超微盘及微半球电极上准稳态可逆波、准可逆波及不可逆波电流方程式.根据导出的准稳态电流方程,提出了一个测定动力学参数的新方法.对理论公式也进行了实验验证.
Under quasi - steady - state conditions, the general current equations of the chronoamperometry and cyclic voltammetry at disk and hemispherical microelectrodes were derived by solving the partical differential equations. A quantitative meaning of quasi - steady -state or steady - state process for chronoamperometry at disk or hemispherical microelectrode is given and examplified. Many experiments are carried out to verify the validity of the results. The methods for the determination of heterogeneous rate constant and charge transfer coefficient are also developed.
