An existing radiochemical NAA procedure for Cd, Co, and Cu was improved to allow determination of individual radiochemical yields by the radioisotopic tracer technique, thus eliminating errors owing to variable recovery. 109Cd was used as tracer for Cd determination via 115Cd/115mIn, 57Co for Co via 60Co, and potentially for Ni via 58Co, whereas as a novelty 67Cu, produced by reactor irradiation of ZnO of natural isotopic composition (by the 67Zn [n,p] 67Cu reaction) was used for Cu via the indicator nuclide 64Cu. The simple production and purification of 67Cu by anion exchange is described. Results for biological RMs are given and discussed.
一种现有的用于镉、钴和铜的放射化学中子活化分析方法得到了改进,以便通过放射性同位素示踪技术测定各个放射化学产率,从而消除由于回收率变化而产生的误差。109Cd用作通过115Cd/115mIn测定镉的示踪剂,57Co用作通过60Co测定钴的示踪剂,也可能用作通过58Co测定镍的示踪剂,而作为一种新方法,由天然同位素组成的ZnO经反应堆辐照产生的67Cu(通过67Zn[n,p]67Cu反应)用作通过指示剂核素64Cu测定铜的示踪剂。描述了通过阴离子交换简单制备和纯化67Cu的方法。给出并讨论了生物参考物质的结果。
