Determination of Quinoline in Textiles by Gas Chromatography－ Mass Spectrometry

Abstract

A method for the determination of quinoline in textiles by gas chromatography-mass spectrometry(GC－MS) was developed. The experimental conditions for extraction were optimized. The textile samples were ultrasonically extracted with toluene as organic solvent. The extraction solution was filtered with 0.45μm polytetrachloroethylene filter membrane, and the filtrate was subjected to GC-MS. Under the optimal conditions, the linear correlation coefficient of this method was 0.9998, with a low detection limit of 0.1 mg/kg  in the concentration range of 0.1-1.0 mg ·L-1. Recoveries ranged from 82. 9% to 92.0 % with RSDs ranged from 1.4% to 3.8%.
