尽管 Rh 是工业上重要且最昂贵的铂族金属 (PGM)，但从 PGM 混合物中选择性优先分离 Rh 仍然是一个巨大的挑战。在这项工作中，研究了使用含间苯二胺的沉淀剂 (m-PDA) 在盐酸 (HCl) 溶液中将 Rh (III) 与 Pd (II) 和 Pt (IV) 分离。在高HCl浓度（6.0-8.0 M）下，大部分Rh（III）（>90%）沉淀，而Pd（II）和Pt（IV）几乎不沉淀（
Although Rh is an industrially important and the most expensive platinum group metal (PGM), the selective and preferential separation of Rh from PGM mixtures still remains as a big challenge. In this work, the separation of Rh (III) from Pd (II) and Pt (IV) in a hydrochloric acid (HCI) solution was studied using a m-phenylene diamine-containing precipitant (m-PDA). At high HCI concentrations (6.0-8.0 M), most of the Rh (III) (>90%) was precipitated, and Pd (II) and Pt (IV) were hardly precipitated (
