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).
