| 中文摘要: |
| 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0100mg/L～250mg/L范围内线性良好，二乙胺、三乙胺的方法检出限均为002mg/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968%～101%，6次测定结果的RSD为01%～19%。 |
| 英文摘要: |
| Air in workplace was collected by porous glass plate absorption tube， and the contents of diethylamine 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%. |
