Abstract: To solve the problem of simultaneous determination of multiple phenols in textiles, a method for the determination of 17 phenols in textiles was developed by gas chromatography-mass spectrometry (GC-MS). The sample was extracted with potassium hydroxide (2 mol/L) by ultrasonic; the extract was reacted with acetic anhydride. The derivative was extracted by hexane and determined by GC-MS. Data were acquired in the selected ion monitoring (SIM) mode and quantified by internal standard method. Good linearity was obtained at the mass concentration range of 0.05~0.5 μg/mL with a correlation coefficient (r2) above 0.9990. The limits of quantification (LOQs) were 0.05 mg/kg, the average recoveries were in the range of 89.3%~117.6 % for 17 phenols with the relative standard deviations below 9.3 %. This method is accurate and sensitive, and it is suitable for the analysis of 17 phenols in textiles.
