摘要：

This paper discusses the development of a separation method for isolation of Tm-171 from a half-gram irradiated erbium target in support of stockpile stewardship and astrophysics research. The developed procedure is based on cation exchange separation using alpha-hydroxyisobutyric acid (alpha-HIBA) as chelating agent. It is able to achieve either a decontamination factor of 1.4(4) x 10(5) with 68.9(3) % recovery or 95.4(3) % recovery with a decontamination factor of 5.82(7) x 10(3) for a mock 500-mg target containing 17.9 mg thulium in a single pass-through at room temperature.
