Abstract: The invention discloses a preparation method for a morin molecularly imprinted silica gel. A morin molecule is adopted as the template, acrylamide or methacrylic acid is taken as the functional monomer, and silica gel surface grafting imprinting technology is employed to synthesize morin molecularly imprinted silica gel. The preparation method includes three steps: (1) preparation of N-propyl maleamic acid modified silica gel; (2) synthesis of a morin molecularly imprinted silica gel primary product; and (3) purification treatment of morin molecularly imprinted silica gel. The morin molecularly imprinted silica gel prepared by the method has high adsorption capacity and good selective adsorption properties. Experiments validate and summarize that morin imprinted silica gel has a good recovery rate on actual samples, and therefore has good application prospects in molecular recognition, enrichment, separation, detection and other aspects.
