摘要

日本大部分铂族金属精炼厂都采用溶剂萃取法对铂族金属进行相互分离。虽然在20世纪70年代建立了一些工业工艺，但很少发现有效的工业用萃取剂。近年来，一些化合物被报道为实用的PGM萃取剂，以及PGM萃取机理的新概念。本文综述了以溶剂萃取法为基础的PGM回收工艺、工业萃取剂及其性能、PGM的常规提取机理。此外，我们讨论了最近有趣的萃取系统(酰胺型化合物和离子液体)，然后介绍了基于金属配合物在有机相的外球的特定相互作用的新萃取概念。(doi: 10.2320 / jinstmet.JE201604)

Recent Research in Solvent Extraction of Platinum Group Metals

Most of the refineries for platinum group metals (PGMs) in Japan have adopted solvent extraction methods for mutual separation of PGMs. Few effective extractants for industrial use have been found although some industrial processes were established in 1970's. Recently, some compounds have been reported as candidates for practical PGM extractants in addition to new concepts for PGM extraction mechanisms. In this review article, we present well–known PGM recovery processes based on solvent extraction, industrial extractants and their properties, and conventional extraction mechanism for PGMs. Additionally, we discuss recent interesting extraction systems (amide–type compounds and ionic liquid) and then introduce new extraction concepts based on the specific interactions at the outer–sphere of a metal complex in the organic phase.
