Determination of Trace Gold in Plant Samples from a Gold Mining Area by Graphite Furnace Atomic Absorption Spectrometry with Ascorbic Acid as the Matrix Modifier

Determination of Trace Gold in Plant Samples from a Gold Mining Area by Graphite Furnace Atomic Absorption Spectrometry with Ascorbic Acid as the Matrix Modifier

Determination of low-level gold in geochemical samples by Graphite Furnace Atomic Absorption Spectrometry (GFAAS) has good accuracy. However, this method is limited to the determination of trace gold in plants due to the large sample amount of > 20 g required, incomplete ashing in the muffle furn...
