| Abstract: | To digest a sample in a mixed acid of HNO 3 and HClO 4 with the ratio of 3 to 1 in a determining arsenic flask with a reflux tube; then, determination by flow injection hydride generation atomic absorption spectroscopy. The RSD is less than 9.6%; the added rate of recovery of sample is between 95.1%～99.6%, the minimal detectable concentration of the method is 0.39～0.79ng/ml. It has high sensitivity and stability and its precision and accuracy are up to the standard of microanalysis. |
