近年来国内极谱分析工作者对固体电极的应用做了大量的工作,如石墨电极、炭糊电极、玻璃石墨电极、金、铂、银为基体的汞膜电极等。固体电极用于阳极溶出分析具有独到之处。我所曾把银基汞膜电极用于正向极谱测定矿石中的锌,经多年生产表明,效果令人满意。可是如遇铜含量高的试料,由于生成Zn—Cu金属互化物而降 In recent years, domestic polarographic workers have done a great deal of work on the application of solid electrodes, such as graphite electrodes, carbon paste electrodes, graphite electrodes, gold, platinum and silver as the substrate. Solid electrode for anodic dissolution analysis is unique. I have used silver-based mercury film electrodes for the positive polarographic determination of zinc in ores, which, after years of production, have shown satisfactory results. However, in case of high copper content of the sample, due to the formation of Zn-Cu intermetallic compounds down
