| Abstract: | A method is reported for the determination of trace bismuth in traditional chinese medicine by hydride generation atomic fluorescence spectrometry. The effect of different means of digestion, the medium amounts of acid and reducing agent on the determination of Bi is investigated. In the given conditions, the linear range of determination is 0.1-200 microg x L(-1), and the detection limit is 0.0946 microg x L(-1). The instrumental relative standard deviation is about 0.55% and the recovery is about 94%-107%. The method is accurate, rapid and convenient with satisfactory results. |
