Abstract:
Removal of organic dyes from water by adsorption is one of the most effective methods because of its easy operation, cost-effectiveness and high efficiency. In this study, superparamagnetic nickel ferrite-polyethylenimine (Ni0.40Fe0.60Fe2O4-PEI) nanocomposites were synthesized for removal of organic dyes. Superparamagnetic nickel ferrite colloidal spheres were prepared by economical and green hydrothermal method and then co-polymerized by PEI. X-ray diffraction (XRD) pattern of nanoparticles showed a pure phase of Ni0.40Fe0.60Fe2O4 and the average crystallite size of 12 nm. The magnetic properties of nanoparticles were measured by vibrating sample magnetometer (VSM). The magnetic hysteresis curves of nanoparticles demonstrated no definite remnant magnetization or coercivity and exhibited superparamagnetic behavior at room temperature. The FT-IR results showed ferrite nickel is coated by polyethyleneimine (PEI). Furthermore, it is indicated that use of nickel ferrite with magnetic properties and polyethylenimine as a cationic polymer in this nanocomposite removes methyl blue (MB) from water.
