| Abstract: | Objective： To establish a method to determine hair mercury level by high pressure digestion-atomic fluorescence spectrometry. Methods： The hair samples were digested by hydrogen peroxide and nitric acid after washing. The hair mercury concentration was determined by atomic fluorescence spectrometry under the selected working condition. Results： The detection limit was 0.008 μg/L. The concentration had a good linear range （0.4-2.0 μg/L）, the correlation coefficient was 0.999 8. The relative standard deviation was 0.95%, and the average recovery of the standard was from 97.5% to 102.8%. Conclusion： This method has high sensitivity and good accuracy, and is suitable for determination of mercury in hair. |
