The determination of silver in silicate rocks by electrothermal atomic absorption spectrometry
January 1, 1979
Silver is extracted from a 20% tartaric acid solution by using butyl acetate and diphenylthiourea, and the organic layer is analyzed directly by the graphite-furnace technique. The precisions is ca. 8% as estimated from multiple analysis of 13 standard rocks; there are no systematic errors. The detection limit is 2.4 ppb for 250-mg samples.
