OBJECTIVE: To establish the method of atomic fluorescence spectrometry (AFS) after alkali fusion for determination of tin dioxide in workplace air.
METHODS: Tin dioxide in workplace air was collected with microporous membrane, directly digested by alkali fusion with solid sodium hydroxide heated by electric furnace, and determined by AFS.
RESULTS: The linear range of tin dioxide (as Sn) determined by AFS was 1.5~100 μg/L (excluding zero) , and the correlation coefficient was 0.9993. The detection limit of this method was 0.5 μg/L, the lower limit of quantification was 1.5 μg/L, and the minimum detectable concentration was 0.05 mg/m(3) (the volume of the air sample was 75 L) . The relative standard deviation was 1.94%~3.55%, and the average recovery of standard addition was 95.0%~96.0%.
CONCLUSION: The method of AFS after alkali fusion for determination of tin dioxide in workplace air is proved to be simple, rapid, sensitive, and accurate, with complete digestion.
