Synthesis, Characterization, and Application of Magnetized Lanthanum (III)-Based Metal-Organic Framework for the Organic Dye Removal from Water

A hybrid composite based on metal-organic framework (MOF) was chemically fabricated by embedding the magnetic Fe3O4 nanoparticles within amino-functionalized porous La-MOF (MOF/NH2) to produce a highly efficient and reusable of MOF/NH2/Fe3O4. Different proper techniques were used for characterization surface morphology chemical arrangement prepared MOF/NH2/Fe3O4 composite. The results using various including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscope (SEM), Brunauer, Emmett, Teller analysis (BET), vibrating sample magnetometer (VSM) approved successful fabrication MOF with amino arms its besides well magnetization nanoparticles. showed enhanced adsorption capacity (618 mg/g) toward methyl orange (MO) anionic dye which is higher than many commercial reported adsorbents due presence types sites (NH2 groups lanthanum sites), large area MOF, synergetic effect Moreover, selective MO from mixtures owing electrostatic attraction. Also, retained over 90% efficiency removal even after six successive cycles. So, present study provided practical strategy design functional composites. Furthermore, adaptability architectural form, it potential adsorbent material industrial wastewater treatment uses.
