摘　　要：采用固相微萃取-气相色谱法建立了测定废水中三乙胺和苯胺的方法,对萃取条件和气相色谱条件进行了优化.方法的相对标准偏差为0.5 %～0.8 %,加标回收率为96.3 %～107.0 %.总分析时间小于1 h,适用于快速分析废水中胺类化合物.An analytical method of the solid phase microextractiongas chromatography was developed to determine triethyamine and benzenamine in waste water, and the extraction conditions are optimized. The results shows that the average recoveries of triethylamine and benzenamine are 96.3 % and 107.0 %, and the relative standard deviations of them are 0.5 % and 0.8 %, respectively. The proposed method is simple, fast, solvent free and can be applied to determine the amines in waste water.
