Effect of post-purifications treatments on cellulose nanocrystal isolated from Oil Palm Mesocarp (OPM) biomass / Muhammad Syafiq Mohammad

Cellulose nanocrystal (CNC) has been isolated from oil palm mesocarp (OPM) using standard sulfuric acid hydrolysis method followed by three different post¬ purification treatment. These three post-purifications treatment been produce three different end products which is CNCl, CNC2 and CNC3. The effect of post¬ purifications treatment on the cellulose nanocrystal were determined using FTIR, UV-Vis, Chroma Meter and SEM. During the FTIR analysis there four major peak that been observed which is at the region of 3600 to 3200 cm-1 ,2900 cm-1 , 1700 cm-1 and at 1100 to 600 cm-1• This all peak is importance in conforming the CNC. While in UV-Vis, to indicate the successfully isolated of CNC the light intensity must over 75% in range of 350 to 800 nm. In SEM, the rod-like structure ofCNC was observed.
