Publication number: CN101985493

Abstract: The invention discloses a preparation method of cyhalothrin molecularly imprinted polymer, orderly including the following steps: 1) dissolving a beta-cyclodextrin as functional monomers in a solvent, and then, adding a cyhalothrin as molecular templates for stirred reaction at room temperature; 2) adding a isocyanate compound as a cross-linking agent in a mixed liquor obtained from the step 1) for reaction with magnetic stirring; 3) washing the reaction products of the step 2) with an ultrasonic extraction method to remove the cyhalothrin, the un-reacted beta-cyclodextrin, the isocyanate compound and the solvent; 4) processing products of the step 3) with centrifugation, vacuum filtering and drying, and milling the obtained blocky high polymers into grains which are the cyhalothrin molecularly imprinted polymers.; The cyhalothrin molecularly imprinted polymers can be used for High-selectivity enrichment and separation and purification of trace amount of the cyhalothrin in environmental samples or plant samples.
