We present the production of Co on a small, 13 MeV medical cyclotron utilizing a siphon style liquid target system. Different concentrated iron(III)-nitrate solutions of natural isotopic distribution were irradiated at varying initial pressures and subsequently separated by solid phase extraction chromatography. The radio cobalt (Co and Co) was successfully produced with saturation activities of (0.35 ± 0.03) MBq μA for Co with a separation recovery of (75 ± 2) % of cobalt after one separation step utilizing LN-resin.
我们在一台小型的 13 MeV 医用回旋加速器上利用虹吸管式液体靶系统生产了钴。用不同浓度的天然同位素分布的三价铁硝酸盐溶液在不同的初始压力下辐照，然后用固相萃取色谱法分离。成功地用天然同位素分布的三价铁硝酸盐溶液制备了放射性钴（Co 和 Co），Co 的饱和活度为（0.35 ± 0.03）MBq μA，经 LN 树脂一步分离后钴的分离回收率为（75 ± 2）%。
