Objective:
To develop a method to determine mercury by electric heat digestion and atomic fluorescence spectrometry.
Methods:
After electric heat digestion using aqua regia, the soil samples were determined by atomic fluorescence spectrometry.
Results:
The linear range of the method was from 0 to 50 microg/L. The correlation coefficient was 0.9994. The detection limit of the method was 0.0051 microg/L. The relative standard deviations ranged from 1.55% to 6.52%. Four soil samples for quality control were determined by this method and all of the results were in the range of the true values.
Conclusion:
The optimized method have many advantages, such as high sensitivity, few interferences, wide linearity. At the same time,it is simple and rapid.
