【Abstract】 OBJECTIVE To synthesize a molecular imprinting polymer selective for Cefathiamidine. METHODS Different monomers and porogens were investigated and the binding characteristics of the template polymer were evaluated.RESULTS The polymer taking 4-vinylpyridine (4-VP) as an interacting monomer and toluene as a porogen exhibits high affinity to the substrate, Cefathiamidine. CONCLUSION Molecularly imprinted polymer can be used in solid phase extraction and represent clinical utility for enrichment and determination of trace Cefathiamidine.更多还原
