摘　　要：采用气相色谱-质谱(GC-MS)法同时测定纺织品中9种有机锡。应用液液萃取提取纺织品中的有机锡,通过四乙基硼化钠衍生后,采用GC-MS总离子流和选择离子进行测定。结果表明,该方法线性相关性好,9种有机锡的相关系数R2大于或等于0.9990,回收率均在80%～120%之间,RSD低于7.5%,该方法检测限在0.0039～0.0753mg/kg之间,可很好应用于纺织品中有机锡的检测。The gas chromatography-mass spectrometry （GC-MS） was used for simultaneous determination of 9 organotin compounds in textiles, which involved liquid-liquid extraction of organotin compounds from textiles, derivatization with NaBEt4 and analysis of the ethyl organotin by GC-MS in scan mode and selective ion mode. The linearity response of all organotin compounds were well and R^2≥ 0.999 0. The average recovery was in the range from 80% to 120% and the RSD was below 7.5%. The detection limit ranged from 0.003 9 mg/kg to 0. 075 3 mg/kg. The proposed method has been successfully applied to the determination of organotin compounds in textiles with satisfactory results.
