Abstract:
Objective To establish a method for determination of tellurium(Ti)in the air of workplace by microwave digestion-HG-AFS. Methods The air samples were collected by micropore filters and the concentration of tellurium was determined by microwave digestion-HG-AFS. Results In this method, the linear range was 0.11-40.0 ?g/L, the detection limit was 0.11 ?g/L, the lowest detected concentration of tellurium was 0.000 09 mg/m3(based on 30 L air sample), the rate of recovery was in the range of 95.5%-98.2%, the RSD was less than 3%. Conclusion The method is rapid, accurate, sensitive and suitable for the determination of tellurium in the air of workplace.
