以酸性氧化铝为吸附剂，制备了一个１１８ＭＢｑ的１８８Ｗ－１８８Ｒｅ发生器，并对发生器性能进行了为期４个月的检测。结果表明，１８８Ｒｅ的淋洗产额在８０％—９０％之间，１８８Ｗ的穿透率约为１．０×１０－４％。由于采用了较大高径比的交换柱，使１８８Ｒｅ的放射性比活度较高，能满足用于放射免疫治疗研究的抗肿瘤单克隆抗体标记的要求。
A 188 MBq 188W-188Re generator was prepared using acidic alumina as adsorbent, and the generator performance was tested for 4 months. The results showed that the elution yield of 188Re was between 80% -90% and that of 188W was about 1.0 × 10-4%. Due to the adoption of the exchange column with larger aspect ratio, the specific activity of 188Re is higher, which can meet the requirement of anti-tumor monoclonal antibody labeling for radioimmunotherapy research.
