电化学式分析仪器有悠久历史,广泛应用于各个领域。近年来由于工业流程控制和自动监测的需要,出现了各种形式的电化学流通池,不仅实现了水相和气相介质中的连续自动监测,而且提高了方法的灵敏度和选择性。 1.常用电化学流通池简介 (1)极谱流通池:极谱流通系统最早出现在1940年。用于极谱流通池的电极有滴汞电极和固体电极。 Electrochemical analytical instruments have a long history, are widely used in various fields. In recent years, due to the needs of industrial process control and automatic monitoring, various forms of electrochemical flow cells have emerged, which not only realize continuous automatic monitoring in aqueous and gaseous media, but also improve the sensitivity and selectivity of the method. 1. Introduction to common electrochemical flow cell (1) polarographic flow cell: Polar distribution system first appeared in 1940. The electrode used in the polarographic flow cell has a drop of mercury electrode and a solid electrode.
