| Abstract: | A molecularly imprinted polymer(MIP) using cyromazine as a mimic template,methacrylic acid as the functional monomer and ethylene glycol dimethacrylate as the cross-linker was synthesized with bulk polymerization,and showed high cross-recognization to melamine.It was used to separate,enrich and cleanup melamine from eggs via a molecularly imprinted solid-phase extraction(MISPE) protocol.For gas chromatography/mass spectrometry(GC/MS) analysis,extracted melamine was derived with Sylon BFTTM prior to selected... |
