| 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. |
