A gas chromatography-mass spectrometric（GC-MS） method was developed for the determination of 1,2-dichloroethane in textiles.The samples were extracted with methanol under ultrasonic assistance.The separation and quantification of 1,2-dichloroethane were achieved on an TG-624 column（30 m×0.32 mm×1.8 μm） using temperature programming.The identification and quantification of 1,2-dichloroethane were performed by GC-MS under full scan and selected ion monitoring scan with the external standard method.The result indicated that the calibration curve showed a good linear relationship between peak area and concentration of 1,2-dichloroethane in the range of 0.05-30 mg/L,with a correlation coefficient of 0.999 3.The limit of detection was 0.50 mg/kg.The average recoveries of 1,2-dichloroethane from 7 typical textile matrices including viscose fiber,polyester,wool,nylon,ramie,polyacrylonitrile fiber and cotton,at three spiked concentration levels of 0.5,1.0,5.0 mg/kg were in the range of 85.2%-101.4% with relative standard deviations（RSDs） of 4.0%-7.4%.With the advantages of low detection limit,good accuracy and high precision,the method could be used for residue surveillance of 1,2-dichloroethane in textile samples.
