| Abstract: | The determination method of trace Au in geochemical exploration sample,ie,the graphite furnace atomic absorption spectrometry(SFAAS) methed after preconcentration with polyurethane foam,is interpreted in this paper.The trace Au is absorbed with polyurethane foam under the presence of Fe 3.The Au is determined by SFAAS with ascorbic and ammonium nitrate as the matrix modifier.This method has been applied to the analysis of Au in the geochemical exploration sample and the result is satisfactory. |
