| Abstract: | Objective To establish a method for determination of Bismuth （Bi） in the air of workplace by hydride generation atomic fluorescence spectrometry （AFS）. Methods The parameters in this method were optimized by experiment. Results The detection limit of this method was 0. 03 μg/L,and the lowest concentration was 5.0 ×10^-5mg/m^3 ,digestion rate was 99. 8% - 102. 5% ,the RSD was 1.6%, and the correlation coefficient was O. 999 7. Conclusion The operation of this method is simple and quick. The method can be absolutely applied in the determination of Bi in workplace air. |
