摘要/Abstract

摘要： 建立超快速液相色谱/串联质谱联用法测定生态纺织品中分散黄1、分散黄3、分散黄9、分散黄39和分散黄49等5种黄色分散染料的分析方法。样品经甲醇超声提取后，采用超快速色谱柱，用乙腈和乙酸铵（2mmol/L）溶液作为流动相，梯度洗脱分离。采用电喷雾（ESI）离子多反应监测（MRM）进行质谱分析。5种分散染料在1.0~100.0 μg/kg之间均具有良好的线性，回归系数均大于0．999，检出限(LOD)在0.5~1.0 μg/kg之间。加标回收率在84.5%~106.2%之间，其相对标准偏差在1.2%~6.4%之间。所建方法快速、简便、灵敏、专属性强，能满足生态纺织品中分散染料的监测要求。

Abstract: To establish a method for the determination of five yellow disperse dyestuffs，such as Disperse Yellow 1，Disperse Yellow 3，Disperse Yellow 9，Disperse Yellow 39 and Disperse Yellow 49 in ecological textile by ultra-fast liquid chromatography coupled with tandem mass spectrometry (UFLC-MS/MS)．After the sample is extracted by methanol，the extract is separated on an ultra-fast liquid chromatography column by gradient elution with water and acetonitrile．Detection was carried out by UFLC-MS/MS using electrospray ionization interface in the multi-reaction monitoring (MRM) mode．Calibration curves were linear within the range of 1.0~100.0 μg/kg with the correlation coefficients of more than 0.999，and the limits of quantification （LOQs）were between 0.5~1.0 μg/kg．The extraction recoveries of the five disperse dyestuffs are at 84.5%~106.2%， and the RSDs were between 1.2%~6.4%.The developed method is 　quick，simple，sensitive and specificity for the satisfactory determination of disperse dyestuffs in ecological textile．
