摘要：

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. Cd-109 was used as tracer for Cd determination via Cd-115/In-115m, Co-57 for Co via Co-60, and potentially for Ni via Co-58, whereas as a novelty Cu-67, produced by reactor irradiation of ZnO of natural isotopic composition (by the Zn-67 [n,p] Cu-67 reaction) was used for Cu via the indicator nuclide Cu-64. The simple production and purification of Cu-67 by anion exchange is described. Results for biological RMs are given and discussed.
