用滴汞电极进行电解的方法是在1922年研究成功的,在1924年制出了第一架极谱仪。1925年科学杂志上第一次出现了已为现在大家熟知的极谱图。但是直到三十年代末,极谱方法才在分析化学中得到比较广泛的应用。现在已发表的极谱方法研究文献已经超过八千篇。叙述极谱学的成就以前,首先必须正确地规定“极谱学”的概念。作者的意见认为极谱学是一种科学,它被用来研究在表面能够更新的汞电极上所进行的过程。它不仅研究电流与电压间的曲线关系,也研究其他如单个汞滴的“电流时间”曲线、“电势时间”曲线、电毛细管现象与电解质旋动等的数量关系。除极谱仪外,极谱法应用的仪器还包括显微镜、弦线电流计与阴极射线示波器。微小汞滴所
The method of electrolysis with the drop mercury electrode was successful in 1922 and the first polarometer was made in 1924. For the first time in the 1925 science journal, a polarogram that has become familiar to everyone now appears. However, it was not until the late 1930s that polarographic methods were widely used in analytical chemistry. Now published polarographic method research literature has more than eight thousand. Before describing the achievements of polarography, we must first of all correctly define the concept of “polarography.” The author’s opinion is that polarography is a science that has been used to study the processes carried out on mercury electrodes that are renewed on the surface. It investigates not only the current-voltage curve but also the other current-voltage curves such as single mercury drop, “potential-time” curve, electrocapillaries and electrolyte swing. In addition to the polarography, polarographic instruments used include microscopes, chord ammeter and cathode ray oscilloscope. Micro-mercury drop by
