Analytical Mehtod for Aromatic Amine in Water Using Solid-Phase Extraction and GC/MS

Twenty four aromatic amines were analyzed by gas chromatography-mass spectrometry (GC/MS) coupled the solid-phase extraction (SPE) technology. The result shows that the method is reliability, sensitivity and accuracy. The detection limitation is lower than 0.36 μg/L. The optimum SPE conditions was Envi-chromp colume and pH 8—10 water, eluted two times with CH₂Cl₂. The average recovery of most compounds in blank water is 88.8%—111.8%, and RSD is 6.8%—9.9%. Thirteen drink waters were detected using this method. The result is that all target compounds are under detection limit. It is indicated in degradation test, and most aromatic amine are stable in water for more than fourteen days.
