ABSTRACT
OBJECTIVE: To improve the standard detection method of tin and its compounds in the air of workplace.METHODS: During the sample preparation,the amount of sulfuric acid for air filter membrane digestion was reduced from its original 0. 5 m L( the standard method of flame atomic absorption spectrometry) to 0. 2 m L and no acid-driving after the membrane was digested. The amount of sulfuric acid given to the series of standards was the same as that of the membrane digestion. The samples were detected by the flame atomic absorption spectrometry method. RESULTS: The improved method showed a good linear range of tin as 0. 0-80. 0 mg / L,the regression equation was
