Publication number: CN101747506

Abstract: The invention relates to a method for preparing a molecularly imprinted polymer enriched with trace enrofloxacin, which comprises the main technical key point that enrofloxacin is used as a template molecule, 3-aminopropyl triethoxysilane is used as a functional monomer, tetraethoxy silane is used as a crosslinking agent, an activated silicon ball is used as a carrier, N,N-dimethylformamide is used as a pore-foaming agent, and a surface molecular imprinting technique and a sol-gel technique are utilized to synthesize an adsorptive functional material having high selectivity to the enrofloxacin. The method has a low cost and a simple synthetic process, the reaction condition is easy to control, and the prepared enrofloxacin molecularly imprinted polymer can be used for the combination of solid phase extraction enrichment and high efficiency liquid chromatography, and is suitable for performing online detection on the trance enrofloxacin in animal-based foods and performing purification treatment on various samples.
