Determination of Trace Gold in Geochemical Samples by Flame Atomic Fluorescence Spectrometry with PUFP Separation and Enrichment

BACKGROUND The detection sensitivity, stability, and linear range of Au using flame atomic fluorescence spectrometry (FAFS) is comparable to the method of inductivity coupled plasma-mass spectrometry (ICP-MS). When Au concentration is below 0.5ng/g, it is difficult to accurately determine Au if the...
