Abstract :
In this study, Fourier Transform Infrared Spectroscopy (FTIR) was used to investigate the acetylation of groundnut husk and sugarcane bagasse. Equilibrium isotherm data were analyzed using the Langmuir and Freundlich isotherms. The regression coefficient (R2) values for acetylated groundnut husk (0.997),raw groundnut husk(0.991),acetylated sugarcane bagasse (0.986),and raw sugarcane bagasse (0.985) for Freundlich model was higher than that obtained for Langmuir model which shows that freundlich model is suitable for explaining the sorption equilibrium of crude oil on the adsorbents. Acetylated groundnut husk and sugarcane bagasse are therefore recommended for further development for oil spill cleanup.
