Abstract:
[Objective] To establish a method to determine hair mercury by atomic fluorescence spectrometry after microwave digestion.

[Methods] Hair samples were prepared by microwave digestion and mercury contents in hair samples were determined by atomic fluorescence spectrometry.

[Results] The detection limit of this method for hair samples was 0.026 μg/L for mercury. The specification curve correlation coefficient was 0.999 5. The relative standard deviation was 1.89%-3.23%, and the average recovery ranged from 92.0% to 98.7%.

[Conclusion] Strengths of the study lie in the ideal experimental conditions and the accurate, sensitive, and simple method it finally built which applies to the detection of samples in large amount.
