Neutron activation analysis of trace copper, zinc and indium in geological and meteoritic samples, using rapid chemical separations
For the determination of trace Cu, Zn and In in rock samples, a simple and convenient scheme of RNAA is presented. In this scheme, relatively short-lived nuclides,64Cu,69mZn and116mIn are radiochemically purified immediately after the irradiation of samples. Although the sensitivity for Zn and In is lower in this scheme than that in the RNAA using65Zn and114mIn at a higher neutron fluence, the present radiochemical procedures are simpler and were proved to be highly effective for the determination of these elements in most terrestrial igneous rocks and meteorite samples.
