本文指出了各种方法，其中铂族金属（PGM）的化学可以被操纵，以实现分离使用溶剂萃取技术，并不打算是一个全面的审查已发表的工作。PGM和贱金属的化学差异被强调，因为后者存在于炼油厂液体中。溶剂萃取过程的机制进行了讨论，并与铂族金属络合物化学。溶剂萃取比传统的选择性沉淀工艺的潜在经济优势被认为是。
This paper indicates the various ways in which the chemistry of the platinum group metals (PGM) can be manipulated to achieve separations using solvent extraction techniques and is not intended to be a comprehensive review of published work. Differences in the chemistry of PGM and base metals are emphasised as the latter are present in refinery liquors. Mechanisms of solvent extraction processes are discussed and related to PGM complex chemistry. Potential economic advantages for solvent extraction over conventional selective precipitation processes are considered.
