摘　　要：建立了气相色谱-串联质谱法快速测定全棉织物、聚酯织物、羊毛织物、腈纶织物、合成革织物、棉和氨纶复合织物、羊毛和腈纶复合织物、棉和聚酯复合织物、羊毛和聚酯复合织物9类生态纺织品织物中24种禁用偶氮染料的检测方法。不同种类的纺织品根据成分的不同进行了不同的前处理过程,然后用甲醇进行定容。考察了不同样品基质对回收率的影响,方法的定量限为0.05~0.20 mg/kg,不同基质不同浓度的加标回收率在29.4%~102.8%之间(添加水平为0.20、0.40、1.0 mg/kg,n=6),相对标准偏差<6.8%,该方法的检出限小于我国和欧盟检测标准中对24种禁用偶氮染料的限量要求。A rapid determination method was developed for 24 banned azo colourants in cotton fabric,polyester fabric,wool fabric,acrylic fabric,synthetic leather fabric,compound fabric of cotton and spandex,compound fabric of wool and acrylic,compound fabric of cotton and polyester and compound fabric of wool and polyester by gas chromatography-mass spectrometry. The different pretreatment process were used depend on difference of textures of cotton fabric. Finally samples was diluted with methanol. The influence of different sample matrix on recovery was investigated. The limits of detection of method were 0. 05 - 0. 20 mg/kg for different compounds,the recoveries of different matrixes and concentrations ranged from 29. 4% - 102. 8% at the spiked levels of0. 20,0. 40 and 1. 0 mg/kg. The relative standard deviations were less than 6. 8%. The detection limit of above methods was less than the limited requirements of testing standards of China and European Union.
