Method for detecting acrylamide in water

The invention belongs to the field of water treatment application and discloses a method for detecting acrylamide in water. The method comprises the following steps: (1) transforming acrylamide in a to-be-detected water body into acrylamide bromide derivatives; (2) regulating the pH value of the solution obtained in the step (1) to 1.5-2.5, and adding sodium sulfate; (3) immersing a CAR/PDMS extraction membrane into the solution obtained in the step (2) so as to extract the acrylamide bromide derivatives, wherein the extraction time is 43-50 minutes, and the extraction temperature is 49-59 DEGC; and (4) feeding the CAR/PDMS extraction membrane obtained in the step (3) after extracting the acrylamide bromide derivatives into a GC/MS (Gas Chromatography-Mass Spectrometry) analytical instrument, and detecting and analyzing to obtain the detection results, wherein the analysis temperature is 250-280 DEG C, and the analysis time is 3-7 minutes. According to the method disclosed by the invention, acrylamide with th
