Abstract:
Objective:To establish an atomic fluorescence detection method for bismuth and bismuth telluride (Bi 2Te 3) in the air of workplaces. Methods:In March 2024, the acetate-fiber filter material was digested by ultrawave and detected by atomic fluorescence spectrometry to obtain the content of bismuth and Bi 2Te 3 in the air of the workplace. Results:The correlation coefficients of standard curve were above 0.9990, The detection limit of bismuth was 0.02 μg/L, the minimum detection concentration was 0.02 μg/m 3, the minimum quantitation concentration was 0.06 μg/m 3, the minimum detection concentration and the minimum quantitation concentration of Bi 2Te 3 was 0.03 μg/m 3 and 0.09 μg/m 3 respectively. The digestion efficiency ranged from 98.6% to 102 %, the RSDs of intra-batch and inter-batch were below 1.3% and 4.0% respectively. The samples were stable within 7 days, and interference elements of 1.0 mg/L (Ag, Al, As, B, Ba, Be, Cd, Co, Cr, Cs, Cu, Fe, Ga, Li, Mg, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sn, Sr, Ti, Tl, V, Zn, Zr) do not affect the detection of bismuth. Conclusion:This method is simple, fast, accurate, and highly sensitive, and can meet the requirements of the determination of bismuth and bismuth telluride in the air of working place.
