对于贵金属的分析,钯是研究得比较多的一个。在国外分析杂志上每年都发表不少于数十篇文章。其中有机试剂得到最广泛的应用,无论在灵敏度及选择性方面都比无机试剂优越。本文只准备讨论与钯产生有颜色反应的有机试剂,对于作重量分析用的无色沉淀反应就不加以叙述了。钯与有机试剂作用形成的有色产物,有些可溶于水,直接进行分光光度测定;有些 For the analysis of precious metals, palladium is one of the more studied. In foreign analysis magazine every year published no less than dozens of articles. One of the most widely used organic reagents, both in terms of sensitivity and selectivity superior to inorganic reagents. This article is prepared to discuss only organic reagents that produce color reactions with palladium. The colorless precipitation reaction for gravimetric analysis is not described. Palladium and organic reagents formed by the formation of colored products, some soluble in water, direct spectrophotometry; some
