摘　　要：P507-ROH(异辛醇)体系分离制备高纯Lu_(2)O_(3)工艺已成为离子型稀土矿重稀土分离的主流工艺技术。本文综述了近10年来中国科学院长春应用化学研究所在P507-ROH体系萃取重稀土的热力学机理、界面动力学传质机制、平衡酸度调控技术、非平衡态级数补偿技术、ROH含量快速分析方法、镥分离工程示范和离子型稀土矿铒/铥分组工艺等研究进展及工业应用,对Lu_(2)O_(3)萃取分离工艺的发展提出了展望。The separation and preparation of high purity lutetium oxide by P507(2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester)-ROH(isooctanol)system have become the main technology for heavy rare earths separation from IREO(ion-adsorption rare earth ores). This article summarizes the research progress and industrial application of heavy rare earths extraction by P507-ROH system of Changchun Institute of Applied Chemistry,Chinese Academy of Sciences in recent ten years,such as thermodynamic mechanism,interfacial kinetic mass transfer mechanism,equilibrium acidity control technology,non-equilibrium stages compensation technology,ROH concentration rapid analysis method,lutetium oxide separation engineering demonstration and Er/Tm grouping process of IREO,and puts forward the prospect of the development of lutetium oxide extraction separation process.
