Application of polyaniline-based magnetic-dispersive-solid-phase microextraction combined with liquid chromatography tandem mass spectrometry for the evaluation of plastic migrants in food matrices

Magnetic nanoparticles of Fe3O4 coated with polyaniline have been synthesised through chemical coprecipitation, and successfully characterised using different techniques such as FT-IR and X-ray diffraction. Such nanocomposite was applied as sorbent for a new magnetic micro-dispersive solid phase extraction procedure for the extraction of seven plastic migrants in jelly samples.
