气相色谱－质谱联用对纺织品中16种含氯酚及邻苯基苯酚、β-萘酚残留量的测定

A GC-MS method was developed for the determination of 16 chlorophenols, o-phenyphenol and β-naphthol in textiles. The sample was extracted with methanol in ultrasonic bath. The extract was concentrated and redissolved in 0.1 mol/L borax solution, then was derivatized by acetic anhydride and extracted by hexane. The target of compounds were analyzed by GC-MS with internal standard method. The result indicated that the calibration curves showed good linear relationships between the peak area and concentration in the range of 0.05~1.0 mg/L for o-phenyphenol (OPP) and β-naphthol (B-N), and 0.025-1.0 mg/L for the rest of analytes. The correlation coefficients were in the range of 0.9993-0.9999. The average recoveries of 16 chlorophenols, o-phenyphenol and β-naphthol from the contton sample spiked at three concentration levels of 0.05, 0.1, 0.5 mg/kg ranged from 83% to 112% with relative standard deviations of 0.26%-8.82%. The method was simple, rapid and sensitive, and was suitable for the determination of 16 chlorophenols, o-phenyphenol and β-naphthol in the import and export of textiles.
