A novel fiber-assisted emulsification microextraction (FAEME) method was developed for the determination of eight aromatic amines (AAs) in aqueous samples. In this method, the extraction solvent (100 muL chlorobenzene) and the dispersive material (1.0mg kapok fiber fragments) were added successively into the aqueous sample (5.0 mL), and then the mixture was emulsified by ultrasound to form the cloudy solution. Phase separation was performed by centrifugation, and the sedimented phase was transferred to micro-inserts with a microsyringe for analysis. All variables involved in the extraction process were identified and optimized. By coupling the analysis with gas chromatography-mass spectrometry (GC-MS), excellent detection limits (0.01-0.2 mug L(-1)), good precision (RSDs, 3.33-6.56%) and linear ranges (0.10-160 mug L(-1) and 1.0-160 mug L(-1)) were obtained. Compared with the traditional solvent-emulsification method, the extraction recoveries of the proposed method were much higher. Satisfactory recoveries were achieved when the method was used for the analysis of AAs in spiked real water samples.
