Adsorptive Removal of Arsenic From Aqueous Solutions Using Amino Functionalized Super Paramagnetic Iron Oxide Nanoparticle/Sio2

The adsorption features of amino functionalized super paramagnetic iron oxide nanoparticle/sio2 for selective removal of arsenic in water is evaluated. amino functionalized super paramagnetic iron oxide nanoparticle/sio2 is synthesized and characterized with fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd), and electron microscope (sem). ftir shows amine group successfully attached to nanoparticle. xrd-diffraction pattern shows that the magnetic phase of super paramagnetic nanoparticle is magnetized by inverse spinel crystal structure. sem image was used to study the morphology of super paramagnetic nanoparticle. the adsorption capability of the nanoparticle was examined in batch system. the nanoparticle was applied to removal of arsenic from aqueous media. it was shown that the adsorption of arsenic on the nanoparticle was depended on ph and contact time.
