Abstract


This research aimed to create nano cellulose from bagasse by simple method and equipment. Nano celllulose were isolated from bagasse in three distinct stages. Initially, the fibers were treated with 5 wt.%  NaOH solution followed by bleaching using 5 wt.% hydrogen peroxide (H2O2) in alkali condition (pH 11) to remove hemicelluloses and lignin. Then, cellulosic fibers were mechanically separated by using kitchen blender to produce nano cellulose. FT-IR analysis demonstrated that the treatments could separate gradually of lignin and hemicelluloses from the fiber. FT-IR analysis also indicated a blending result with concentrate of 0.7 wt.% has the highest crystalline structure. This results were also supported by X-ray analysis. X-ray diffraction studies revealed that Nano-cellulose (0.7 wt %) obtained have higher crystallinity (83.75%). The type of cellulose that was formed is cellulose I, as expected. Finally, It could be told that blending by using kitchen blender might be one of an alternative way to produce a nano cellulose.
