Abstract: a b s t r a c tIn this work, phosphatidylcholine (PC) was coated on magnetic nanoparticles to form lipid bilayer as solid-phase extraction (SPE) sorbents for the enrichment of polycyclic aromatic hydrocarbons (PAHs) from environmental water and milk samples. The lipid bilayer was coated on Fe 3 O 4 nanoparticles using a modified dry lipid film hydration method. The resulted Fe 3 O 4 /PC could be readily isolated from solution with a magnet, and exhibited excellent adsorption performance to organic pollutants.…
