摘要：

Chemical separation procedures using solvent extraction methods for the quantitative separation of rare earths from ThO2 have been examined using Dimethyl hexyl phosphoric acid (HDEHP) / HNO3, HDEHP / HCl, Tri n-octyl phosphine oxide (TOPO) / HNO3 and TOPO / HC1 systems. The efficiency of these systems was determined using radioactive tracers and emission. © 1990, Taylor & Francis Group, LLC. All rights reserved.
