铂族金属溶剂萃取分离新进展

从含氧，硫萃取剂，含磷萃取剂，含氮萃取剂及协萃体系四个方面对近年来铂族金属溶剂萃取进展进行了综述。尽管人们在铂族金属萃取方面开展了一些研究并取得了一些进展，但萃取分离仍存在诸如选择性差和反萃难等诸多问题，能用于实际应用的体系和流程还很少，尚需进一步开展高选择性并易于反萃的萃取剂和萃取体系的研究。

Recent Advance in Solvent Extraction of Platinum Metals Separation

The recent advance in solvent extraction of platinum metals was reviewed on oxygen containing and sulfur containing extractants,phosphorous containing extractants, nitrogen containing and mixed extractants. Some research and achievement were made, but problems such as poor selectivity and difficulties in back extraction are still existed. Those systems and procedures that can be practically used are relatively less. Efforts should be made to find extractants and systems that have higher selectivity and are easy to be back extracted.
