摘要

在室温下，在氯化物体系中，在Cu衬底上成功制备了重量百分比比为7:3的镓镍合金靶材。建立了一种新的两柱无有机溶剂分离方法，用于从高放射性同位素纯度(99.99%)的辐照Ga-Ni合金靶中提取68Ge。采用该分离方法，68Ge的回收率为95±5%，核反应natGa(p,xn)68Ge的产率为0.27±0.02 MBq/μA h。

Efficient extraction of 68Ge from irradiated Ga–Ni alloy via a novel organic-solvent-free separation procedure

In this work, a gallium–nickel alloy target with a weight percentage ratio of 7:3 was successfully prepared on Cu substrate in a chloride system at room temperature. A novel organic-solvent-free separation procedure based on two columns for extracting 68Ge from irradiated Ga–Ni alloy target with high radionuclidic purity (99.99 %) was developed. By this separation procedure, the recovery of 68Ge is 95 ± 5 % and the yield of 68Ge via the nuclear reaction natGa(p,xn)68Ge was measured to be 0.27 ± 0.02 MBq/μA h.
