摘要

建立了纺织品中喹啉和异喹啉的气相色谱-质谱检测方法。采用乙酸乙酯为溶剂，超声提取，经蒸发浓缩和定容后，以GC-MS测定。结果表明，喹啉和异喹啉在0.05~10.0 mg/L范围内线性良好(r>0.999 0)，回收率为82.0%~99.8%，相对标准偏差(n=6)为0.9%~3.8%;方法的定量下限为0.05 mg/kg。该方法灵敏度高、简便、高效、准确，可以满足纺织品中喹啉和异喹啉的检测需求。

Abstract

A method was developed for the determination of quinoline and isoquinoline in textiles by gas chromatography-mass spectrometry(GC-MS).The experimental conditions for extraction were optimized.The textile samples were ultrasonically extracted with ethyl acetate as organic solvent.After being concentrated by evaporation and set to a certain volume

the extracts were determined by GC-MS.Under the optimal conditions

the calibration curves for quinoline and isoquinoline were linear(r>0.999 0) in the concentration range of 0.05-10.0 mg/L.Recoveries were in the range of 82.0%-99.8% with their relative standard deviations(RSD

n=6) of 0.9%-3.8%.The limits of quantitation were 0.05 mg/kg.The method was sensitive

simple

efficient and accurate

and could meet the requirements for detection of quinoline and isoquinoline in textile products.
