Abstract
Aim to separate patulin (PTL) from its co-extracted 5-hydroxymethylfurfural (HMF), using 6-hydroxyni-cotinic acid as template substitute molecular, a molecularly imprinted polymer (MIP) was prepared by grafting on silica bead surface. The preparation of the MIP was assayed by infrared spectrometry(IR) and elemental content detection, and the absorption characteristic of the polymer was investigated by solid phase extraction-high performance liquid chromatog-raphy(SPE-HPLC)analysis and oscillation adsorption detection. The results indicated that synthesized polymers had specific adsorption to patulin as compared with HMF-the adsorption rate in the SPE method and the absorbance in the oscillation adsorption to PTL were 93.97% and 0.654 fxg/mg separately, while to HMF they were 76.89% and 0.496 u,g/mg respectively. The polymer can be effectively applied as SPE coupled with HPLC for the determination of patulin in apple juice or related apple products.关键词
