Magnetic solid phase extraction with CoFeb>2b>Ob>4b>/oleic acid nanoparticles coupled to gas chromatography-mass spectrometry for the determination of alkylphenols in baby foods
In situ acetylation of the alkylphenols provided a good GC separation. Magnetic nanoparticles functionalized with oleic acid efficiently preconcentrate the APs. Most of the baby food samples analyzed were free from the studied APs.
