| titleOfInvention | Preparation method and application of diquat molecularly imprinted polymer microspheres |
| abstract | The invention belongs to the technical field of herbicides, and particularly relates to diquat molecularly imprinted polymer microspheres and a preparation method and application thereof, wherein the preparation method comprises the following steps: dissolving a mixture of alpha-methacrylic acid and methyl methacrylate and diquat in a solvent according to a molar ratio of 5-10:1, performing ultrasonic treatment, adding a cross-linking agent, filling nitrogen to remove oxygen, sealing, performing prepolymerization at 0-4 ℃, transferring a prepolymer into a polymerization reactor, adding column chromatography silica gel and an initiator, fully oscillating, filling nitrogen to remove oxygen, and sealing; reacting in a constant-temperature water bath oscillator, cooling, placing in a refrigerator, adding hydrofluoric acid, stirring, filtering, washing, and drying to obtain solid precipitate; and (3) Soxhlet extracting the solid precipitate with a eluting solvent until the residue of the diquat cannot be detected by the washing liquid, stopping washing, and drying to constant weight. The diquat molecularly imprinted polymer microspheres are used as SPE column fillers, so that the diquat pesticide residue in plant-derived food can be effectively detected, and the quality safety of edible agricultural products is guaranteed. |
