摘　　要：89SrC l2具有良好的应用前景,可通过89Y(n,p)89Sr反应制备89Sr。研究了Y2O3靶在300#反应堆照射后形成的辐照产物、辐照混合物中杂质核素的去除方法,以及纯化过程中带入有机杂质的清除方法。结果表明,靶件辐照后产生了88Y及86Rb等杂质核素,通过TBP萃取能将辐照混合物的Y浓度降到0.001 mol.L-1以下;通过P204萃淋树脂的吸附,可将Y浓度降低到1×10-8mol.L-1以下;通过HZ-803大孔径吸附树脂能有效去除过程中带入的有机杂质;通过HZ-001阳离子交换树脂能有效去除辐照混合物中的86Rb,同时使89Sr(NO3)2转型为89SrC l2。The ^89y （n, p）^89 Sr reaction is the most advanced procedure of ^89Sr production. This paper discussed the irradiation contents of ^89Y2O3 target irradiated in 300^# reactor and tried to give a simple purification procedure of ^89SrC12. The results indicated that the only impure nuclides were ^89Y and ^89Rb. The ^89Sr purification research showed that the concentration of y^3＋ could reduced to 0. 001 mol · L^-1 by TBP extraction and then could be reduced below 1 x 10^-8 mol · L^-1 by P204 extraction chromatograph. The organic impurity introduced with extraction could be removed by HZ - 803 large caliber resin. The HZ - 001 cation - exchange resin could removed the ^89Rb impurity and transformed the ^89Sr（ NO3 ）2to ^89SrC12.
