摘要：

A method for the determination of 15 elements in high-purity silver with detection limits ranging from 10-4 to 10-1 μ9'9-1 has been developed. Despite the high cross section of silver for neutrons, the analysis remains accurate and simple. Accuracy was achieved by a calculation of the thermal and epithermal neutron-flux attenuation, including the shadow effect on the standards placed in the vicinity of the sample. The high radioactivity of the matrix was separated by a chemical method using mainly inorganic fixators (nickel ferrocyanide and antimony pentoxide). Radioactivity measurements were then performed by γ spectrometry. Analytical results for silver samples are given. © 1979, American Chemical Society. All rights reserved.
