Synthesis and characterization of amine functionalized mesoporous magnetite nanoparticles having environmental applications

In this study, amino functional groups were chemically bonded to the surface of newly synthesized KIT-6 mesoporous magnetite nanoparticles (MMNPs) by post-toluene reflux synthesis method. This method treats calcined mesoporous nanoparticles with the functional organosilanes. Physical and chemical structures of the synthesized mesoporous magnetite nanoparticles were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and nitrogen adsorption- desorption isotherms. Finally, the ability of the newly synthesized aminated mesoporous magnetite nanoparticles as a novel and recoverable sorbent with environmental applications was examined by studying the removal of dichromate ions from aqueous samples.
