Abstract: The invention discloses a preparation method of glucan gel surface Sudan red molecularly-imprinted adsorption material, and the application of the glucan gel surface Sudan red molecularly-imprinted adsorption material in selective adsorption and separation of Sudan red molecules in food analysis. The method takes glucan gel as a supporter, and Sudan red molecularly-imprinted polymer is modified on the surface of the supporter. The preparation method is mainly and technically characterized by comprising the steps of: adding Sudan red, ethylene glycol dimethacrylate, azodiisobutyronitrile and sulfydryl glucan gel according to a certain proportion; in acetonitrile medium, removing oxygen by inert gas, carrying out reaction at the constant temperature, filtering and washing; carrying out Soxhlet extraction for 8-12h by 0.4-0.8mol/L of hydrochloric acid-ethanol solution to remove Sudan red template molecules; and finally, washing and drying to obtain the glucan gel surface Sudan red molecularly-imprinted adsorption material. The material has specific recognition capability on the Sudan red molecules, is high in selectivity, rapid in adsorption speed, good in desorption performance, biodegradable and simple in technology, has regeneration capacity and has the advantages of being environment-friendly and the like.
