Abstract
In this article, we determined the composition of commercial cellulose by
IR spectroscopy using a Shimadzu B8400S FTIR spectroscope (Oujda- Morocco).
Commercial cellulose contains absorption bands between wavelengths 3391 and
609cm-1. This cellulose contains the functional groups: C-H, C-O.
Infrared (IR) spectroscopy was applied to analyze the chemical composition and
structural characteristics of commercial cellulose. The obtained IR spectrum
exhibited distinct absorption bands corresponding to the functional groups
typical of polysaccharides. Major peaks were observed at approximately 3330 cm⁻¹ (O–H stretching vibrations), 2900 cm⁻¹ (C–H stretching), 1640 cm⁻¹ (absorbed water), and 1050 cm⁻¹ (C–O–C and C–O stretching), confirming the
presence of β‑1,4‑glycosidic linkages in the cellulose structure. The absence
of additional bands associated with lignin or hemicellulose indicates high
purity of the commercial sample. These results demonstrate that IR spectroscopy
provides a fast, accurate, and non‑destructive method for identifying the
molecular composition and assessing the purity of cellulose materials.
