| Abstract |
A novel core–shell magnetic surface molecularly imprinted polymer with folic acid as
a template was successfully synthesized by the sol–gel method. To generate Lewis acid sites
in the silica matrix for the interaction of the metal coordinate with the template, 3-
aminopropyltriethoxysilane was used as a functional monomer, tetraethyl orthosilicate as a
cross-linker, and aluminum ions as a dopant. The magnetite encapsulated by the silica shell
plays an important role as a magnetic-coated polymer. The synthesized product was
characterized by powder X-ray diffraction, scanning electron microscopy, transmission
electron microscopy, and FTIR and UV/Vis spectroscopy. The powder X-ray diffraction,
FTIR and UV/Vis spectra confirmed the characteristics of the as-prepared silica coated
magnetite and Folic acid molecularly imprinted polymer. It was successfully applied for
magnetic solid-phase extraction prior to the determination of folates in tomato samples using
high-performance liquid chromatography with photodiode array detection. The detection
limit of the proposed method was 1.67 µg L−1, and results were satisfactory, with a relative
standard deviation of <3.94%. |
