The present study has aimed at investigating some local agricultural wastes as sources for the production of a-cellulose; these included: sugarcane bagasse, rice straw, durra stalk and groundnut shell. A mixture of toluene and ethanol in the ratio of 2:1 was utilized in solvent extraction, for 6 hr, to remove wax and resins, leaving the fibrous material. This was then delignified by treatment with acidic sodium chlorite (NaClO2) solution. Alkaline hydrolysis (18% NaOH) was employed to remove hemicelluloses leaving a-cellulose. The isolated final product was characterized using Fourier Transform Infrared (FTIR) Spectroscopy. The ?-Cellulose content of the four selected plants, (sugarcane-bagasse, rice straw, durra stalk and groundnut shell, were 40.3%, 39.3%, 42.7%
