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 between 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%.
