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 0～80μg•L-1with a correlation coefficient of 0.9995,while the detection limit was 0.036μg•L-1,the relative standard deviation was 1.9% .Trace total arsenic in the samples was 0.145～0.376μg•g-1 and a recovery range of 83.9%～108.5% were obtained. |
