摘要：

A procedure is described for the preconcentration and determination of trace Cu, Co, Zn, Cd and Hg in water. The metals were enriched on poly(acrylamidoxime) chelating resin and determined by instrumental neutron activation analysis and atomic absorption spectrometry. The metals were quantitatively recovered in the concentration range 10-500 ng ml-1. The enrichment factor was 400.
