| Abstract | Corn husk is one of the agricultural residues which are abundant, inexpensive, and readily available source of renewable lignocellulosic biomass. Cellulose nanocrystals (CNCs) were extracted from corn husk by alkali and bleaching treatments followed by sulfuric acid hydrolysis treatment. The material obtained after each stage of the treatments was characterized. Morphological investigation was carried out using scanning electron microscope (SEM) and transmission electron microscopy (TEM). Fourier transform infrared (FTIR) spectroscopy showed the progressive removal of non-cellulosic materials. The crystallinity of corn husk and CNCs was also investigated using X-ray diffraction analysis (XRD). The highest crystallinity index value of this study is 68.33% for cellulose nanocrystals. |
