摘要
本文提出以2-乙基己基膦酸-2-乙基己脂(P507)萃取柱色谱分离,EDTA络合滴定混合稀土中单一稀土元素,并应用于多种混合稀土氧化物中单一稀土的全分析。本方法所需设备简单,分析结果准确可靠。
Single rare earth element was separated from mixed rare earth oxides with 2-ethylhexyl hydrogen-2-cthylhexyl phosphonate (P507) extraction chromatography and then titrated with EDTA. This method was applied to the determination of single rare earth elementin many types of mixed rare earth oxides. The equipments were simple. The results were precise and reliable.
