【Abstract】 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.更多还原
