中文摘要: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。

Simultaneous Determination of 19 Chlorinated Phenols in Textiles by Liquid Chromatography-Mass Spectrometry
Abstract: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.
