Abstract
Peels of sugarcane are agrarian wastes, obtainable in a large quantity and are currently underutilised. This work was set out to discover the possible usage of sugarcane peel as a source of cellulose and nanocrystalline cellulose, hence, solving the problem of littering waste of sugarcane peels arbitrarily in the environment. Isolation of cellulose from sugarcane peel was prepared by using two pretreatments methods; alkaline and acidified sodium chlorite treatment. The extraction of cellulose nanocrystals (CNCs) was performed via acid hydrolysis at 45oC for 45 mins by 64% concentration sulphuric acid. The chemical composition of the sample was studied. The resulting CNCs of the sugarcane peel were characterised using; Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) spectroscopy and Transmission electron microscopy (TEM). The results indicated that the hemicellulose and lignin were removed comprehensively from the extracted cellulose. FT-IR andXRD revealed free noncelluosic contents and enhanced crystallinity for CNCs, respectively. The TEM revealed 20.6±9.47 nm as average particle size in width,a needle-like shape and a uniform nano dimension bundle of crystals. As a result, the CNCs from sugarcane peel residuals are of high-quality and auspicious resources for various industrial applications.
