Abstract

Silica  coated magnetite  nanoparticles were  covalent  grafted with  3-aminopropyl trimethoxysilane  to give APTSCMNPs. Reaction of  the resulted nanomaterial with 4-formyl benzo-12-crown-4 ether afforded FB12C4/APTSMNPs  nanocomposite  material  in  which  the  crown ether  moiety  was  attached  through  propyl  chain  spacer. Characterization of  the prepared nanocomposite was performed with different  physicochemical  methods  such  as  FT-IR  spectroscopy, thermogravimetric  analysis  (TGA-DTA),  X-ray  diffraction  (XRD), scanning  electron  microscopy  (SEM),  transmission  electron microscopy (TEM) and vibrating sample magnetometry (VSM).
