Cellulose-,Fe, 3 O 4 nanocomposite has been successfully synthesized by modifying ,Fe, 3 O 4 onto nanocellulose acetate surface derived cellulose from rice husk. It was supported by Fourier Tranform-Infrared (FT-IR) characterization, where there was absorption at 900 cm −1 , which was a characteristic for cellulose absorption, and at 572 cm −1 , which was the absorption of ,Fe,-O.
