近几年来,示波极谱方法的研究已经取得了不少成绩,但银汞固体电极在电流-电压型(单扫式)示波极谱中的应用,则尚未有研究报导。我们认为:这种电极表面应具有与滴汞电极相似的极谱性能,探讨这种电极在示波极谱方法条件下的一些性能,将有助于寻求一种适合于分析用途的固体电极。一、实验技术1.仪器装置我们装置了电流-电压型(单扫式)示波极谱仪,仪器中加于电解池两端的电压以每秒0.6至50伏的速度
In recent years, there have been many achievements in the research of oscillopolarography. However, the application of silver-mercury solid electrode in current-voltage (single sweep) oscillopolarography has not been reported yet. In our opinion, the electrode surface should have similar polarographic performance as the drop mercury electrode. To explore some of the properties of this electrode under the oscillopolarographic method will help to find a solid electrode suitable for analytical purposes. First, the experimental technology 1. Instrument Installation We have a current-voltage type (single swept) oscilloscope polarography, the instrument plus the voltage across the cell at a rate of 0.6 to 50 volts per second
