近年来,对含微量的所有铂族金属在分析化学上均取得相当的成就。曾发表过一系列的评述,报道了这些金属的富集和测定方法。评述中所引证的大多数资料,仅以典型的溶液作试验。这些方法用于实际生产,要费很长时间,而且还未必能证实它们在度量衡方面的特性。因此,我们提出这篇使人感兴趣的方法评述,建议用于测定不同类型的矿物原料,组份复杂的溶液和工业产品中的铂族金属。现代分析技术最大的难题是测定10~(-7)～10~(-3)%铂族金属,也就是说,在被认为铂族金属较贫的物料中,测定这些金属是困难的。
In recent years, considerable achievements have been made in analytical chemistry for all platinum group metals containing traces. Has published a series of reviews, reported the enrichment and determination of these metals. Most of the information cited in the review is tested only with typical solutions. These methods are used for actual production and take a long time, and they may not yet be able to confirm their characteristics in terms of weights and measures. Therefore, we present this interesting methodological review, which is recommended for the determination of different types of mineral raw materials, complex solutions and platinum group metals in industrial products. The biggest challenge with modern analytical techniques is the determination of 10 -7 to 10 -3% PGM, which means that it is difficult to determine these metals in materials that are considered poorer PGMs.
