| description | The invention relates to the fields of analytical chemistry and food safety and in particular relates to a preparation method of a cyanuric acid molecular imprinting solid-phase extraction column filling material. The preparation method of the cyanuric acid molecular imprinting solid-phase extraction column filling material comprises the following specific steps: adding reaction raw materials, namely a cyanuric acid template molecule, 4-vinyl pyridine and an ethylene glycol dimethacrylate crosslinking agent into an ethanol pore-forming agent and water, uniformly mixing, then adding an azodiisobutyronitrile initiating agent, degassing, introducing nitrogen, then sealing, and carrying out a reaction for 20-48 hours at the temperature of 40-80 DEG C, so as to obtain coarse molecularly imprinted polymer; grinding the coarse molecularly imprinted polymer until the granularity is 15-80 microns, performing Soxhlet extraction by use of a mixed solvent composed of ethanol, acetic acid and water, and then repeatedly wa |
