钴的同位素~(57)Co不仅可以标记博来霉素(Bleo-mycin)和维生素B_(12)等化合物,而且还可以用来制备穆斯堡尔源。最近几年,穆斯堡尔效应的研究越来越广泛。因此~(57)Co的研制和生产方法引起了人们的重视。我们选用铁作靶材(在铜的衬底上电镀铁),氘核为轰击粒子,产生核反应:~(56)Fe(d,n)~(57)Co,~(56)Fe(d,a)~(54)Mn,~(57)Fe(d,2n)~(57)Co,~(57)Fe(d,n)~(58)Co,。本文针对上述体系采用异丙醚-TBP萃取除铁,阴离子交换精制纯化~(57)Co,
Cobalt isotope ~ (57) Co can not only label bleomycin (Bleo-mycin) and vitamin B_ (12) and other compounds, but also can be used to prepare Mossburg source. In recent years, the study of Mossbauer effect has become more and more widespread. Therefore, the development and production of ~ (57) Co has aroused people’s attention. We choose iron as the target (electroplated iron on the copper substrate), deuteron bombardment of particles, the nuclear reaction: ~ (56) Fe (d, n) ~ (57) Co, a) ~ (54) Mn, ~ (57) Fe (d, 2n) ~ (57) Co, ~ (57) Fe (d, n) ~ (58) Co. In this paper, the above system using isopropyl ether-TBP extraction of iron, anion exchange purified ~ (57) Co,
