| Abstract: | Using hydride-atomic fluorescence spectrometry determined tin content in the waste gas.Choose a more efficient and safe nitric acid-hydrogen peroxide electric hot plate digestion system for sample pretreatment, adjust the best instrument parameters to determine. Research showed that：in 0-10 μg/L linear range, correlation coefficient can reach 0.999 6, the method detection limit is0.003 μg, the addition standard recovery is 92.7%-95.9%, RSD≤2.1. Using hydride-atomic fluorescence spectrometry to determine tin in exhaust gas has the advantages of high sensitivity, less interference, wide linear range, simple operation, and fast. |
