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. |
