摘要
研究了用CL-P507-HCl体系萃取色层法分离铒、铥、镱,考察了树脂粒度、溶液温度、淋洗液酸度、树脂负载量、进样质量比等条件对分离效果的影响。结果表明,铥、镱之间存在着萃取抑制现象;以1.65 mol/L盐酸淋洗铒,1.90 mol/L盐酸淋洗铥和镱,在溶液温度50℃时可实现3者的分离;以99.9%氧化铥为原料,单柱一次分离可获得高纯铥溶液。
The separation of Erbium, Thulium and Ytterbium by extraction chromatography with Cl- P507-HCl system has been studied. The effects of particle size of resin, temperature,concentration of eluant,loading and proportioning of rare earth ions have been discussed. The extraction restraint between thulium and ytterbium has been observed. The 99. 995% of high purity thulium oxide has been prepared using 99.90% of raw.
