摘　　要：使用体积分数5%的丙酮水溶液为萃取剂,采用快速溶剂萃取仪萃取纺织品中的有机磷。萃取到丙酮水溶液中的有机磷用碳纳米管吸附后,采用少量二氯甲烷将其从碳纳米管中洗脱,洗脱液中的有机磷用气相色谱-质谱联用仪测定。该法可同时测定纺织品中的12种有机磷,方法的平均加标回收率为75%~95%,相对标准偏差（RSD）在8%以内,检出限小于0.5 mg/kg,满足分析要求。The organophosphorus pesticides in textiles were extracted with 5% acetone by rapid solvent extraction. The pesticides in extractant were adsorbed by carbon nanotubes,and then were eluted with a small amount of dichloromethane. The eluent was analyzed by gas chromatography-mass spectrometry. This method was developed for simultaneous determination of twelve organophosphorus pesticides in textiles. The average recoveries of this method were 75% ~ 95%,the relatively standard deviation（ RSD） were less than 8%,and the quantification limits were less than 0. 5 mg / kg,meeting the requirements of analysis.
