用于极谱测定的微量或半微量电解池多为经特殊加工的玻璃制品,Z.P.Zagorski曾作过专门介绍。近代极谱法中所采用的三电极装置有一系列的优点:补偿了电解池回路中的iR降,使内阻较高的参比电极可以使用,被测离子的波形与峰电位稳定,对某些阻抗较高的溶液如稀电解质溶液或非水溶液可以测定。因此,设计一个结构简单,能适用于例行分析的三电极半微量电解池,仍有现实需要。有关三电极的微电解池装置的报导很少。
For the polarographic determination of trace or semi-micro electrolytic cells are mostly processed glass products, Z.P. Zagorski made a special presentation. The three-electrode device used in modern polarography has a series of advantages: it compensates the iR drop in the electrolytic cell loop so that the reference electrode with higher internal resistance can be used; the waveform and the peak potential of the measured ion are stable; Some of the higher impedance solutions such as dilute electrolyte solution or non-aqueous solution can be measured. Therefore, it is still necessary to design a three-electrode semi-microelectrolysis cell with a simple structure and suitable for routine analysis. There are few reports of three-electrode micro-electrolysis cell devices.
