摘 要: 本文研究了无机离子交换剂—水合五氧化二锑(Sb2O5·nH2O)的制备,并用它分离了放射性母子体,制备了一个新的201Pb—201Tl放射性发生器。结果表明,末发生器具有高效、快速、简便的特点,此外还讨论了离子交换反应的机理。 Some aspects of the adsorption of carrier-free 201Pb and 201Tl on antimony pentoxide, Sb2O5·nH2O have been investigated. The rusults of static adsorption experiments and their application on column condition are presented. This makes possible the preparation of a 201Pb - 201 Tl generator. The results show that this method gives the high yield, rapid rate and good purity. On other hand the mechanism of the ion-exchange reaction is also discussed.
