铂族合金中铑、钯、金的测定,我室过去采用化学法,分析手续较为繁杂;其中个别合金中的金虽已改用原子吸收法测定,但一种合金的分析,往往需要采用数种方法,甚为不便。为了获得快速、准确的分析结果,拟全部采用原子吸收法直接进行测定。用原子吸收法测定贵金属元素已有不少报道,由于贵金属之间常有一些干扰,特别是对铑的干扰最为严重。为了克服这些干扰,许多作者提出了各种缓冲剂,都有一
Platinum alloys in the determination of rhodium, palladium, gold, my room in the past by chemical methods, the analysis procedures are more complicated; of which the individual alloy gold has been changed to atomic absorption spectrometry, but an alloy analysis, often need to adopt the number Kind of method, very inconvenient. In order to obtain fast and accurate analysis results, it is proposed that all atomic absorption spectrometry be used for direct determination. There are many reports on the determination of noble metal elements by atomic absorption method. Due to the frequent interference between precious metals, the interference with rhodium is the most serious. To overcome these disturbances, many authors have proposed various buffers, all of which have one
