Abstract

The invention relates to the field of analysis and detection, in particular to a method for detecting nitrogen-containing functional monomers in water-soluble acrylic resin. The method comprises the following steps: S1, preparing a water-soluble acrylic resin sample; s2, respectively carrying out Py-GCMS test, FTIR test and organic element analysis test on the water-soluble acrylic resin sample; s3, analyzing a test result, and determining the content of the nitrogen-containing functional monomer in the water-soluble acrylic resin sample. FTIR test, Py-GCMS test and organic element analysis are combined, so that the synthetic monomer in the water-soluble acrylic acid product can be accurately identified and analyzed. By controlling the thickness of the sample and performing coefficient correction on transmittance data of the sample, qualitative and quantitative analysis of nitrogen-containing functional monomers (such as acrylonitrile and acrylamide) in the resin can be realized, the detection result is more accurate, and reliable data support is provided for component analysis of a water-soluble acrylic resin product.
