金和银的极谱分析金和银在地球和生物中的含量很低，加上其性质特殊，利用极谱法测定金和银不如原子吸收法广泛。由于国内外进行了大量的研究工作，极谱法测定金和银取得了较大的成果。吕义广等收集了金银极谱分析的文献，并作了介绍。金的分析；主要使甩三种方法。（１）... Polarographic analysis of gold and silver Gold and silver in the Earth and the biological content is very low, coupled with its special nature, the use of polarographic determination of gold and silver is not as good as atomic absorption spectrometry. Due to a large amount of research work at home and abroad, the polarographic determination of gold and silver has made great achievements. Lv Yiguang collected gold and silver polarographic literature, and made an introduction. Analysis of gold; the main rejection of three methods. (1) ...
