1.前言高纯钯中的微量杂质测定,目前多采用光谱法,但每次取样需几百毫克之多。至于纯金中 Cu、Pb 等杂质的微量测定,早期曾用极谱法,事先将 Au 用异丙醚—氢溴酸萃取分离后,再分别取水相进行测定,方法灵敏度也不够高。至于用阳极溶出伏安法(ASV)测定高纯金、钯中的 Cu、Pb 等微量杂质,目前尚未见文献报道。本文在前文 1. Introduction Determination of trace impurities in high purity palladium, the current use of spectroscopy, but each sampling should be as much as hundreds of milligrams. As for the determination of Cu, Pb and other impurities in pure gold, the polarographic method was used in the early stage. After the Au was extracted and separated by isopropyl ether hydrobromide in advance, the aqueous phase was taken separately for determination. The sensitivity of the method was not high enough. As for the anodic stripping voltammetry (ASV) Determination of high purity gold, palladium, Cu, Pb and other trace impurities, has not been reported in the literature. This article earlier
