Abstract Reversed-phase extraction chromatography employing a Daiflon-supported HDEHP column and HCl as eluent was examined for carrier-free separation of167Tm from a photo-irradiated Yb target and also from particle-bombarded Er and Ho targets. The examination was performed with radioassays of radioactive Tm and Yb tracers and57Co-γ-induced X-ray analysis of Er and Ho. An example of the separation of about 1 mCi of167Tm from a 100 mg irradiated Yb target enriched in168Yb and a procedure for the final preparation for medical use are described. The YbSO4 precipitation could be combined with this chromatographic separation of167Tm from a more massive Yb target of natural abundance, weighing several tens of grams. A procedure for YbSO4 precipitation is also presented in the Appendix.
