铅是对人体有害的元素。因此测定铅是环保、卫生、食品等部门的重要课题。本文是用银汞膜电极阳极溶出伏安法测定水中痕量铅。阳极溶出伏安法,是极谱分析中较新的方法,在这方面,国内外发表了许多研究报告和综述。本文所用银汞膜固体电极的制备方法,参考了Iseal的工作,并作了改进。由于我们使用了大面积银汞膜电极,并用内电解法
Lead is a harmful element to the human body. Therefore, the determination of lead is an important issue of environmental protection, health, food and other departments. In this paper, anodic stripping voltammetry with silver-mercury membrane electrode determination of trace amounts of lead in water. Anodic stripping voltammetry is a newer method in polarographic analysis. In this regard, many research reports and reviews have been published both at home and abroad. The preparation method of silver-mercury film solid electrode used in this paper refers to the work of Iseal and makes some improvements. Because we use a large area of silver mercury electrode, and use electrolysis
