Abstract:
In this study, cellulose was extracted from sugarcane bagasse (SCB) through a convenient five-step treatment, and procedures
were performed. During the alkaline curing process of the extraction of cellulose, NaOH has a concentration of (0.5, 1.5, 2.75, and
4%) and the extraction time (15, 30, and 45 min) at a constant temperature of 120°
C were taken as variables and perfectly
optimized by response surface methodology (RSM) for cellulose with the highest product. (e optimum conditions were found to
be 2.75% NaOH, 120°C, and 45 min with a cellulose yield of 73.71 ± 0.67% cellulose, 17.22 ± 0.82% hemicellulose, and 9.07 ± 0.95%
lignin. (ough most of the lignin was eliminated during the alkaline and dilute acid pretreatment process, the remaining lignin
was removed by a solution treatment of 4% NaOH, and 21.92% H2O2 at 121°C for 44.97 min where the cellulose yield was found as
89.75 ± 0.64%, hemicellulose was 6.15 ± 0.83%, and lignin was 2.65 ± 0.66%. Morphological analysis revealed that the average
diameter of the cellulose was 12.06 µm. (ermal and XRD diffraction analysis showed that the cellulose is thermally stable and has
a crystallinity index of 31.63%. FTIR spectra demonstrate that cellulose was successfully extracted due to the removal of
noncellulose components.
