摘要：

To determine total arsenic in Chinese traditional herbs, a hydride generation atomic fluorescence spectrometry method was developed. The samples were pretreated by digesting system with HNO3-H2O2. The experimental conditions were studied and optimized. Under the optimum conditions, the samples was measured. There was a good linear relationship between the fluorescence intensity and arsenic concentration in the range of 0 similar to 80 mu g.L(-1)with a correlation coefficient of 0.9995,while the detection limit was 0.036 mu g.L-1,the relative standard deviation was 1.9%.Trace total arsenic in the samples was 0.145 similar to 0.376 mu g.g(-1) and a recovery range of 83.9%similar to 108.5% were obtained.
