The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indie that silica has been successfully coated on the surface of Fe3O4 and 3aminopropyl tri methoxysilane compound have been grafted to the surface of silicacoated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic ...
