| Abstract: | 0.2-0.5. g standard soil samples and actual soil samples were selected to determine the contents of As and Hg in soil by microwave digestion-atomic fluorescence spectrometry.The results showed that the relative error for the determination of total As and Hg in standard soil samples was -3.32% and -4.11%, and the relative standard deviation of 5 parallel determinations was 1.66% and 1.85%, respectively. The spiked recovery of actual soil samples was 89.1% and 83.2% ,and the relative standard deviation was 4.70% and 6.95% ,respectively. The method had the advantages of higher accuracy, simple operation, rapid and sensitivity. |
