Preparation and characterization of magnetic Wells-Dawson heteropoly acid nanoparticles for magnetic solid-phase extraction of aromatic amines in water samples
P2W17Fe@APSCMNPs isused for MSPE of aromatic amines prior to GC-FID. Magnetic separation and rapid equilibrium facilitated to shorten analysis time. The method has been developed and validated obtaining good analytical features. The proposed method achieved low LODs and wide linearity for aromatic amines.
