Abstract:
The objective of this work was to isolate cellulose from oil palm fronds (Elaeis guineensis) and its characterization. Isolation using method combining physical treatment and repeated chemical treatments. Alkali treatments were performed using hydrolyzed with 45% H2SO4, respectively. High levels of cellulose were successfully extracted, with 5 grams of cellulose for every 10 grams of raw oil palm fronds. The morphology of the cellulose was investigated using scanning electron microscope (SEM). Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD) The extracted cellulose was found to have smaller diameter (59 – 60 nm) and smoother surface compared to the untreated fibers. The results from FTIR, and XRD indicate that the hemicelluloses and lignin were extensively removed from the isolated cellulose. Alkali treatment helped in removal of hemicelluloses, while bleaching assisted in delignification. The extracted cellulose showed high crystalline index of 68.75% resulted from removal of lignin and hemicelluloses via alkali and bleaching treatments. This isolated cellulose fiber has great properties and can be used in many applications such as reinforcement agent in biocomposite.
