摘　　要：采用多孔玻板吸收管采集工作场所的空气,离子色谱法同时测定样品中的二乙胺和三乙胺。通过优化试验条件,使方法在0.100 mg/L~25.0 mg/L范围内线性良好,二乙胺、三乙胺的方法检出限均为0.02 mg/L。空白样品3个质量浓度水平的加标回收试验表明,二乙胺、三乙胺的加标回收率为96.8%~101%,6次测定结果的RSD为0.1%~1.9%。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%.
