Abstract
Empty fruit bunches fibre (EFB) obtained from palm oil mill was subjected to base pre-treatment with different concentration of sodium hydroxide (0.89M-10.0M) in order to prepare the cellulosic component for hydrolysis process. The SEM micrographs of pre-treated EFB fibre showed tremendous changes in the morphological structure of the fibre. 2.5 M of sodium hydroxide was an economical base for the treatment purpose. The crystallinity of the reacted fibres was decreased as concentration of NaOH increased. A slight reduction in the absorption of the FTIR chromatogram observed for the treated fibre indicated that the cleavage of the lignin and hemicellulose bond has occurred during the treatment process.
