一、概述控制阴极电位电解法是一种很好的电分离和电重量方法,特别是和极谱分析联用,有很大的实用价值。金属材料通过预电解分离基体后,用方波极谱可以测定其中微量或痕量杂质元素,这样就能顺利地解决银基、铜基、铋基、锑基、锡基中一些杂质的测定问题。 Lingane曾设计了机械式的自动控制电位电解仪,但仪器的体积和可靠性不够理想。为了缩减仪器体积和重量,使使用寿命和可靠性有所改善,Lindstrom与Davis设计了用可控硅的控制电位
I. Overview Control of cathodic potential electrolysis is a good method of electrical separation and electrical weight, especially with polarographic analysis, has great practical value. After the metal material is separated by pre-electrolysis, the trace or trace impurities can be measured by square wave polarography, so that the determination of some impurities in silver, copper, bismuth, antimony and tin groups can be successfully solved . Lingane has designed a mechanical, automatic control of potential electrolyzer, but the size and reliability of the instrument is not ideal. In order to reduce the size and weight of the instrument to improve the service life and reliability, Lindstrom and Davis designed the controllable potential with silicon
