Determination of acrylamide in textiles using isotope internal standard method by gas chromatography-triple quadrupole mass spectrometry
A method for the determination of acrylamide in textiles using isotope internal standard method by gas chromatography-triple quadrupole mass spectrometry(GC-MS/MS)is developed.Isotopic internal stan-dard of acrylamide is added into the samples,then ethanol is used as the extraction agent for ultrasonic extrac-tion.The extracts are analyzed by GC-MS/MS using multiple reaction monitoring(MRM)mode.The results show that acrylamide has good linear relationship(R2=0.999 2)in the range of 0.005-20.000 mg/L.The recover-ies are in the range of 90.0%-109.3%,and the relative standard deviations(n=6)are in the range of 1.6%-2.1%.The limit of quantity is 0.025 mg/kg,which can meet the determination requirements of acrylamide in textiles.
