Abstract: | 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 via115Cd/115mIn,57Co for Co via60Co, and potentially for Ni via58Co, whereas as a novelty67Cu, produced by reactor irradiation of ZnO of natural isotopic composition (by the67Zn n,p]67Cu reaction) was used for Cu via the indicator nuclide64Cu. The simple production and purification of67Cu by anion exchange is described. Results for biological RMs are given and discussed. |
