摘　　要：建立了高效液相色谱-串联质谱法测定皮革偶氮染料中25种芳香胺的分析方法。样品经脱脂、还原裂解、固相萃取后,采用高效液相色谱-串联质谱测定,以保留时间和特征离子丰度比定性,外标法定量。25种芳香胺在10~2000ng/L范围内线性关系良好,相关系数均大于0.99,方法检出限为0.08~0.47μg/kg,精密度为1.3%~9.3%,加标回收率为64.5%~94.6%。该方法具有较高的灵敏度和准确度,适用于皮革偶氮染料中芳香胺的检测。An analytical method for the determination of 25 aromatic amines derived from azo colorants in leathers by high-performance liquid chromatography tandem mass spectrometry was established.After degreasing,reduction cracking,and solid-phase extraction,the samples were determined by high-perfor-mance liquid chromatography tandem mass spectrometry.The qualitative analysis of aromatic amines was based on retention time and characteristic ion abundance ratio,while the quantitative result came from ex-ternal standard method.The 25 kinds of aromatic amines all had good linear relationships within the range of 10-2000 ng/L,with correlation coefficients greater than 0.99.The method detection limit of aromatic amines was in the range of 0.08-0.47μg/kg,with a precision of 1.3%-9.3%and a recovery rate of 64.5%-94.6%.The method has high sensitivity and accuracy,and is suitable for the determination of aromatic amines derived from azo colorants in leathers.
