Abstract:
Objective To develop a method for determination of tin in the air of workplace by microwave digestion-HG-AFS. Methods The air samples were collected and the concentration of tin was determined by microwave digestion-HG-AFS and the parameters of atomic fluorescence spectrometry were studied. Results In the optimum condition, the detection limit of tin was 0.3 ?g /L, the lowest detected concentration of tin in the samples was 0.000 1 mg/m3 (based on 75 L air sample), the RSD was 2.7%-3.5%, the rate of recovery was in the range of 96.5%-104.7%. Conclusion The method is rapid, convenient, accurate, sensitive and suitable for determination of tin in the air of workplace.
