摘要
用１６ ＭｅＶ质子轰击１８６Ｗ 同位素靶，经１８６Ｗ（ｐ，ｎ）１８６Ｒｅ 反应生成１８６Ｒｅ。采用酸性Ａｌ２Ｏ３ 柱分离１８６Ｒｅ，并继而通过阴离子交换树脂柱浓缩等处理，得到可供标记用的无载体１８６Ｒｅ的生理盐水溶液。１８６Ｒｅ的总收率约为８５％ ，１８６Ｒｅ 的纯度大于９９．２％ ，１８６Ｒｅ的厚靶产额为１．５９ＴＢｑ／（Ａ·ｈ），１８６Ｗ 的回收率大于９２％ 。
Re is prepared via the 186 W(p,n) 186 Re reaction with 16 MeV protons on enriched isotopic 186 W target. Following separation by Al 2O 3 column, 186 Re is concentrated by anion exchange column, and finally the carrier free 186 Re saline solution is achieved. The overall yield of 186 Re is about 85%, with purity of 186 Re >99.2%. The thick target yield of 186 Re is approximately 1.85 TBq/(A·h), and the 186 W recovery is hiqher than 92%.
