Determination of 17 phenols in textiles by gas chromatography-mass spectrometry

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 using gas chromatography-mass spectrometry(GC-MS).The sample was extracted with potassium hydroxide(2 mol/L) by ultrasonic treatment,and then 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 relation was observed at the mass concentration range of 0.05-0.5 μg/mL with a correlation coefficient(r2) above 0.999 0.The limits of quantification(LOQs) were 0.05 mg/kg,and 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 proven to be accurate and sensitive,and is suitable for the analysis of 17 phenols in textiles.
