Objective To develop a method for the determination of epichlorohydrin(ECH) residues in water from teabag by liquid-phase microextraction-gas chromatography-mass spectrometry(LPME-GC-MS).Methods Epichlorohydrin in teabag water was enriched by hollow fiber liquid-phase microextraction method,separated by gas chromatography and determined qualitatively and quantitatively by mass spectrometry.Results The limit of determination was 0.18 μg/ml and the linear ranges were 0.36~7.30μg/ml(r2=0.999).Takin...
