摘　　要：建立了同时测定纺织品中19种含氯苯酚类化合物的液相色谱-质谱(LC-MS)法。采用甲醇为溶剂,超声辅助萃取纺织品中的含氯苯酚类化合物,经蒸发浓缩和定容后,LC-MS测定,外标法定量。结果表明,19种含氯苯酚类化合物在0. 05～5. 0 mg/L范围内线性关系良好(r> 0. 999 90),平均回收率为80. 3%～104%,相对标准偏差(n=6)为4. 0%～9. 8%。方法的定量下限为0. 05 mg/kg。方法灵敏、简便、高效、准确,可满足纺织品中含氯苯酚类化合物的检测需求。A method was developed for the simultaneous determination of 19 chlorinated phenols in textiles by liquid chromatography-mass spectrometry( LC-MS). The textile samples were extracted with methanol in ultrasonic bath,then evaporated and set to volume. The target compounds were analyzed by LC-MS and quantified by the external method. The calibration curves for 19 chlorinated phenols were linear( r > 0. 999 90) in the concentration range of 0. 05-5. 0 mg/L. The average recoveries were in the range of 80. 3%-104% with their relative standard deviations( RSD,n = 6) of 4. 0%-9. 8%. The quantitation limits were 0. 05 mg/kg. The method was sensitive,simple,efficient and accurate,and could meet the requirements for detection of chlorinated phenols in textile products.
