摘要
This paper uses a foam enrichment of trace gold in geochemical samples, using graphite furnace atomic absorption spectrometry determined trace gold. Sample by burning aqua regia soluble mineral sealed, foam enrichment, thiourea relief and other process improvements and conditions of control, this method has low detection limit, high sensitivity, easy operation, speed, labor intensity, determination of trace gold in geological geochemical samples.
