Air in workplace was collected by porous glass plate absorption tube,and the contents of diethyl-amine and triethylamine in air samples were simultaneously determined by ion chromatography.By optimizing the test conditions,the method had good linearity in the range from 0.100 mg/L to 25.0 mg/L,and the detection limits of ethylamine and triethylamine were both 0.02 mg/L.The spiked recoveries of blank samples at three mass concentration levels of diethylamine and triethylamine were from 96.8％to 101％,and the RSDs of six measurements were from 0.1％to 1.9％.
