Abstract

The disclosure discloses a nicotinamide dummy template surface molecularly imprinted polymer, a preparation method and application thereof, and belongs to the technical field of chemical materials. The preparation method of the disclosure includes the steps of preparing a modified silica gel carrier, preparing a dummy template surface molecularly imprinted polymer and the like. The disclosure uses nicotinamide, a structural analogue of imidacloprid and acetamiprid, as a dummy template to prepare a silica gel surface molecularly imprinted polymer. The polymer not only can effectively avoid pollution caused by the leakage of template molecules, but also can specifically remove imidacloprid and acetamiprid from water-soluble tea extracts. The removal rate of imidacloprid and acetamiprid is greater than 96% and 93%, respectively, and the loss of tea polyphenols in the extracts is less than 10%. In addition, the molecularly imprinted adsorption column prepared by the disclosure can be eluted with ethanol solution, and the eluted adsorption column can be recycled, so the disclosure can be well applied to the preparation technology of tea extracts and has good application prospects.
