Synthesis of magnetic nanoparticles-decorated halloysite nanotubes/poly([2-(acryloyloxy)ethyl]trimethylammonium chloride) hybrid nanoparticles for removal of Sunset Yellow from water

چکیده مقاله

Magnetite nanoparticles (MNPs) were synthesized on the surface of halloysite nanotubes (HNTs) through co-precipitation approach and the achieved nanocomposites were employed as the support of surface polymerization of [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETAC) to obtain a hybrid adsorbent for removal of Sunset Yellow from wastewater. The resulting magnetic nanocomposite was assessed by several characterizations. The X-ray diffraction (XRD) pattern confirmed the synthesis of Fe₃O₄ MNPs on HNTs. The field emission scanning electron microscope (FESEM) images showed that spherical Fe₃O₄ MNPs were successfully synthesized and the energy-dispersive X-ray spectroscopy (EDS) confirmed the presence of Fe element in nanocomposite structure. The solid adsorbent was prepared by the aid of the magnetic HNTs as the support. The vibrating sample magnetometer (VSM) was …
