| Fe2O3 nanoparticles were synthesized by thermal hydrolysis. A cellulose-Fe2O3 nanocomposite was extracted from the peels of mandarin citrus fruit using cellulose as a reducing agent. Small, uniformly distributed crystals were obtained at 60°, pH 8, for the reaction time of 1 h. The physical properties of the samples were analyzed using X-ray diffraction, field emission scanning electron microscope, and a vibrating-sample magnetometer. The Fe2O3 nanoparticles were spherical and uniformly distributed bounded with the fibrous cellulose, the particle size ranged from 28.21 to 35.91 nm. The cellulose-Fe2O3 nanocomposite exhibited a superparamagnetic behavior, while the Fe2O3 nanoparticle demonstrated a ferromagnetic effect. The nanocomposite showed high adsorption capacity after removing Cu(II) and Cd(II) ions from water. |
