This study investigated two classifications of wood cellulose of particle
sizes 300 ?m to 424 ?m and 600 ?m to 849 ?m. The cellulose samples
were characterized using X-ray diffraction (XRD), energy-dispersive Xray
spectroscopy (EDX), and scanning electron microscopy (SEM). The
cellulose crystal revealed a preferred orientation along the (200) plane
for the most prominent peak. The XRD diffractogram revealed an
orthorhombic structure obtained from the powder diffractogram file
(PDF). Furthermore, the crystallinity index and crystalline size were
calculated and the increase in crystalline size of the isolated cellulose
indicated higher thermal stability. The EDX analysis showed chemical
components of carbon (C), sodium (Na), chlorine (Cl), and oxygen (O) in
the isolated cellulose. The morphology of the cellulose appeared as
strings of fibres. The isolated cellulose has applications in the production
of biomaterial, thermal insulating devices, and domestic applications.
