摘要：

Neutron irradiation of naturally occurring Yb produces small amounts of carrier-free Lu-177 activity. Cation exchange chromatography in the displacement development mode using Dowex-50X8, 200-400 mesh resin, and Zn2+ as the separating ion was used to separate Lu-177 produced in a neutron irradiated Yb target. 0.04M alpha-hydroxyisobutyric acid at pH 4.6 +/- 2 and temperature 26 +/- 1 degrees C was used to elute carrier-free Lu-177 in 70% yield and at a radionuclidic purity greater than 99%.
