微电极研究 ⅩⅤ.微带电极及阵列微带电极上的扩散

Investigation on Microelectrodes ⅩⅤ. Diffusion on Microband and Microband-Array Electrodes

本文讨论了微带电极的计时电流、扩散层与时间的关系;研究了微带阵列电极的扩散层交叠情况及其对计时电流的影响;进而对微带阵列电极上电极间的屏蔽效应进行了研究,屏蔽效应与电解时间、电极间距离及电极宽度有关,用已有的实验结果验证了本文的理论分析.

The relationships of chronoamperometric current and diffusion layer with electrolysis time are discussed at microband electrode. The overlap between diffusion layer of microband electrode array and its effect on chronoamperometric current are studied, and the shielding effect on microband-array electrode is discussed. The shielding effect is relevant to the electrolysis time, the distance between electrodes and the electrode width. The theoretical analysis is in agreement with the experimental results in literature.
