Abstract: The invention discloses a preparation method of a nitrosamine sterilization byproduct molecular marker polymer and application. The preparation method comprises the following steps: pre-polymerizing afunctional monomer by using a template molecule, enabling the obtained pre-polymer system and ethylene glycol metacrylic acid ester to react with azodiisobutyronitrile so as to obtain a high-molecular polymer, and performing physical and chemical cleaning on the high-molecular polymer, thereby finally obtaining a nitrosamine sterilization byproduct molecularly imprinted polymer. The obtained molecularly imprinted polymer is regular in morphology, five nitrosamine substances can be adsorbed simultaneously, rapid separation, enrichment and multi-residue detection on the nitrosamine substances in complex water samples are achieved, and good application prospects are met.
