十年前我们发表了一篇有关铂族元素萃取化学的综述文章,评述了截止1968年底前报道的文献资料。本文是这一课题的又一篇综述,收集了1969～1975年间的有关文献。众所周知,铂族金属具有一些独特的性质,如易于生成各种电荷数各不相同的(或不带电的)络合物、可处于不同的价态等等,这些性质为广泛利用萃取法进行提取和分离创造了有利的条件。这些可能性在分析化学中已广为利用,近来在工艺上也有应用。最近几年来,出现 Ten years ago we published a review article on the chemistry of platinum group element extraction and reviewed the literature reported by the end of 1968. This article is another review of this topic, collecting the relevant literature from 1969 to 1975. It is well-known that PGMs have some unique properties such as the ease with which complexes of different charge numbers (or uncharged) can be generated, different valence states, etc., which are widely exploited by extraction And separation has created favorable conditions. These possibilities have been widely used in analytical chemistry and have recently also been applied in the art. In recent years, appeared
