| Abstract: | A method for determination of beryllium and its compounds in the air was established by using GFAAS. Air samples were collected by microporous filtering film which digested by perchloric acid-nitric acid with magnesium nitrate as matrix modifier. Calibration curves of the method exhibited linearity in a range be- tween 0. 100 μg/L and 3.00 μg/L. Detection limit was 1.7× 10 ^-5 mg/m3 （ sampling volume 75 liters）. RSD of 3 levels spiked samples ranged from 3.8% to 4.5%. The recoveries ranged from 93% to 102%. |
