Abstract
Perfluorinated compounds (PFCs) include a large group of man-made chemicals characterized by a fully fluorinated alkyl chain attached with different hydrophilic functional groups (carboxyl or sulfonate group). In recent years, PFCs have been recognized as emerging organic pollutants mainly due to their global distribution, environmental persistence, bioaccumulative ability and potential hazard to human beings. Until now, several adsorptive materials (e.g. crosslinked chitosan beads, anion exchange resins) have been synthesized as effective adsorbents for removal of PFCs from a variety of water samples. However, these materials all have shortcomings and the novel adsorbents with more efficiency for PFCs removal are still required. In this study, functional magnetic nanomaterial, namely [email protected]/APTES&PFOTES, was prepared by a modified Stober method. using poly(acrylic acid)-modified Fe3O4 nanoparticles as support substrate, (3-aminopropyl)triethoxysilane (APTES) and 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFOTES) as functional monomers, core-shell structured [email protected]/ APTES&PFOTES was obtained. Fluorine-fluorine interaction and electrostatic attraction were the two major acting forces for PFCs recognition and [email protected]/APTES&PFOTES exhibited much higher adsorption amounts for PFCs than the other reference compounds. As the following study, [email protected]/APTES&PFOTES will be applied for selective removal of PFCs in environmental, biological and foodstuff samples.
