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.
