Abstract: Abstract: A method was developed for measurement of octylphenol(OP) and nonlyphenol (NP) residues in textile products by gas chromatography-mass spectrometry， which studied the choice of extraction solvent, extracting methods, solid phase extraction conditions and conditions of gas chromatography-mass spectrometry. The study showed that the OP and NP in textile products were detected by n-hexane solvent with ultrasonic-assisted extraction, purified by Supelclean Envi-Carb solid phase extraction column and determined by gas chromatography-mass spectrometry. Quantitative ions were selected at m/z107 for OP and NP, and qualitative ions were selected at m/z206 for OP and m/z220 for NP. The results indicated that under the optimized conditions, the spiked recoveries were 86.20%-106.20%（OP）and 81.10%-91.80%（OP）, and the relative standard deviations(RSDs) for concentration of 0.1mg /kg were 7.81% and 4.56% ( n = 6) . The quantitation limits were 0.1mg /kg. The method was simple, rapid and sensitive, and could meet the relevant requirement of European Union.
