本文试制了一种极谱分析中适用的蜡浸石墨电极,考察了电极应用于测定铅镉时的一些条件,提供了一个测定金属锌中痕量铅镉的分析方法,获得了与一般极谱法准确度相同的结果。
In this paper, a wax-impregnated graphite electrode suitable for polarographic analysis was prepared. Some conditions for the determination of lead and cadmium were investigated. An analytical method for the determination of trace lead and cadmium in zinc metal was provided. Law accuracy of the same result.
