Abstract
In this research, magnetic iron oxide/chitosan/hydroxyapatite (MCSHA) and magnetic iron oxide/hydroxyapatite/chitosan (MHACS) nanocomposites were synthesized and by two methods. Begin, the magnetic nanoparticles of iron oxide were prepared by applying iron 2 and iron 3 by co-precipitate. Then, in the first method, after making magnetic Iron Oxide, the magnetic Iron Oxide was combined with chitosan and finally synthesized with hydroxyapatite. In the 2th method, after the preparation of magnetic iron oxide, it was combined with hydroxyapatite and finally synthesized with chitosan. The adsorbents were characterized by Fourier transform infrared (FTIR) spectroscopy. With both adsorbents, the methylene blue dye removal did and separated adsorbed by a magnetic field external, and were compared by the ultraviolet-visible spectrophotometer. Then, the surface morphology and elemental analysis of the (MCSHA) were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) pattern. Also, the magnetic field it was characterized by vibrating sample magnetometer (VSM) analysis. With regard to the percentage of removal above 1th method, it was used as an adsorbent magnetic iron oxide/chitosan/hydroxyapatite (MCSHA) to remove the methylene blue cationic dye from aqueous solution.
