Determination of Acrylamide in Flocculant by Gas Chromatography-Mass Spectrometry / 环境与健康杂志

ABSTRACT

Objective To develop a method for the determination of acrylamide in flocculant by gas chromatography-mass spectrometry.Methods Acrylamide was derived through bromination and extracted by organic solvent.GC-MS method was used to identify the target substance and quantify acrylamide.Results The recoveries obtained from samples spiked with standards were in the range of 70.2%-109.2% and relative standard deviations (n=5) was less than 5.0%.Linearity of peak area was obtained over a wide range of concentration (4.3-2 000 ?g/ml),and the correlation coefficients was 0.999 4.Conclusion The method is reliable,selective and reproducible and it is applicable to the determination of the acrylamide in flocculant.
