摘　　要：采用分散液液微萃取(DLLME)结合气质联用法(GC-MS)测定染料中21种禁用芳香胺。试验确定了萃取剂和分散剂,并对试剂用量、萃取时间和盐效应等参数进行优化。结果表明,在本试验确定条件下,新方法对染料中21种禁用芳香胺的富集倍数达到79~172倍,检出限为0.3~1.2mg/kg,线性范围为1~50mg/kg,平均加标回收率为86.5%~102.3%,相对标准偏差为2.40%~9.67%。该方法高效快捷、易操作,且减少了有机溶剂使用量,安全环保。Dispersive liquid-liquid micro extraction（DLLME）coupled with gas chromatography-mass spectrometry was used for the determination of the forbidden aromatic amines from dyes.Experimental conditions affecting the micro extraction procedure were optimized,such as types and volumes of extraction and dispersion solvents,extraction time and ionic strength.Under optimized conditions,the enrichment factor（EF）of 21 aromatic amines was 79~172,the limits of detection was 0.3~1.2 mg/kg,the linearity ranges were 1~50 mg/kg.The average recovery of the aromatic amines was 86.5%~102.3% with the relative standard deviation of 2.40%~9.67%.The method had advantages of being quicker and easier to operate,and lower consumption of organic solvent.
