| titleOfInvention | Preparation method of cellulose acetate boron affinity imprinted membrane and its application in the selective separation of shikimic acid |
| abstract | The invention belongs to the technical field of resource utilization and chemical separation, and relates to a method for preparing a cellulose acetate boron affinity imprinted membrane, comprising: mixing N-methylpyrrolidone, cellulose acetate, PVP, PEG-400 and deionized water at 30 React at ~60°C for 5-20 hours, let stand for 12 hours, scrape out the coating film, and freeze-dry; immerse the prepared cellulose acetate film in absolute ethanol, prepare an ethanol solution, add KH570, mix well and add dropwise Soak the cellulose acetate membrane in absolute ethanol, reflux at 50-100°C, wash, and dry naturally; soak the grafted KH570 cellulose acetate membrane in absolute ethanol, add shikimic acid, VPBA, and cross-linking agent EGDMA , Initiator AIBN, react in a nitrogen atmosphere at 50-90°C for 6-36 h, and then dry. The invention applies the prepared cellulose acetate boron affinity imprinting membrane to extract shikimic acid in environmental plants and wastes, and has good application prospects in the field of enrichment and purification of natural products with a cis-dihydroxy structure. |
