Abstract

A rapid method of daughter free Ac$^{227}$ tracer preparation was studied. Through two stage extraction by HDEHP and TBPO, essentially daughter free Ac$^{227}$ tracer can be prepared. Possible loss of Ac$^{227}$ activity during the process was estimated. Milking of Th$^{227}$ from Ac$^{227}$ was also studied.

Ac$^{227}$을 溶媒抽出法에 依하여 그의 崩壞系列元素로부터 分離하는 迅束한 方法을 考察해 보았다. HDEHP 및 TBPO로 二段階抽出過程을 거침으로서 追跡子用으로 充分한 純度를 가진 Ac$^{227}$을 얻을 수 있으며 이들 過程中에 일어날 Ac$^{227}$의 損失程度도 推定해 보았다. Ac$^{227}$으로부터 Th$^{227}$의 milking도 兼하여 實驗하였다.
