| Abstract: | Extractive chromatograph using a TPP column was applied to preconcentration and matrix separation for trace silver in geological samples. A flow injection on-line method for the determination of silver by flame AAS is described. An enrichment factor of 20 was achieved at a sampling frequeucy of 30 times/h. The precision RSD is 2.0% for the analysis of a geochemical standard reference material (GSD-12, n = 11) and the detection limit obtained (3sigma) is 0.02 microg/g. |
