摘要
在四川大学CS-30回旋加速器上通过核反应^(Nat)Cd(p,xn)^(111)In进行了制备放射性核素^(111)In的研究。实验选用高纯度的天然镉作为靶材料,并采用电沉积法制备靶件,研究了辐照靶件的溶解以及放射化学分离方法。结果表明,采用26 MeV的质子轰击天然靶件,并采用CL-P204树脂将In与Cu^(2+)、Cd^(2+)、Zn^(2+)等杂质进行分离,可以得到产额(EOB 48h,即轰击结束48h后)约为25~28MBq/(μA·h)的^(111)In,其放射性核素纯度大于99%,Cu^(2+)和Cd^(2+)等化学杂质总质量浓度小于8.0mg/L。
111in was prepared on the CS-30 cyclotron in Sichuan University via nuclear reac- tion NatCd(p,xn) 111in with natural cadmium target by electro-deposition method. The proce- dures of dissolution and radiochemical separation of the irradiated cadmium target were inves- tigated. The results indicate that the rain of 25-28 MBq/(μA · h) can be obtained using the proton of 26 MeV bombarded on the natural cadmium target, with radiochemical separation of Cu2+, Cd2+, Zn2+, and In by adopted CL-P204 resin. The radionuelide purity of 111in produced by natural Cd is more than 99 %. The total chemical impurity of Cu2+ , Cd2+ , and Zn2+ is less than 8.0 mg/L.
