锗是一种典型的分散元素,常伴生在铅锌矿及煤矿中,含量一般在0.001—0.000X％范围内。对于矿物岩石及烟道灰中的微量锗,一般在6mol/L盐酸中蒸馏出锗或用四氯化碳从9—10mol/L的盐酸萃取分离出锗后,分光光度法测定,不仅操作麻烦,且引起严重污染。多年来,为找寻一种不需分离富集而直接测定锗的快速灵敏的分析方法,是分析生产人员的愿望和要求。极谱法测定锗,虽有一些报导,但灵敏度不够理
Germanium is a typical dispersing element, often associated with lead-zinc and coal mines, the content is generally in the range of 0.001-0.000X%. For trace amounts of germanium in mineral rock and flue ash, germanium is generally distilled off in 6 mol / L hydrochloric acid or germanium is extracted by extraction with 9-10 mol / L hydrochloric acid with carbon tetrachloride, and the spectrophotometric method is not only troublesome to operate , And cause serious pollution. Over the years, a quick and sensitive analytical method for the direct determination of germanium without isolation and enrichment has been to analyze the aspirations and requirements of the producer. Polarographic determination of germanium, although some reports, but the sensitivity is not sensible
