Abstract:
A method of determining trace amounts of gold in rocks by using flame- less atomizer is discribed. The recoveries of gold from the organic phase by back-extraction and effect of background, interfering substance under the op- timum condition were examined. The detection limit is 8.9 × 10-12g of Au. The relative standard deviation for sample containing 0.38g/T is 6.6%(15 deter- minations).
