Abstract

The effects of acidified chlorite (NaClO2) and totally chlorine free (TCF) bleaching were evaluated relative to the properties of microcrystalline cellulose (MCC) fabricated from oil palm empty fruit bunch fibres (OPEFB). The MCC properties were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA) methods, and they were compared with commercial MCC. The results revealed that all MCC belongs to cellulose type 1 and OPEFB-NaClO2-MCC showed a higher crystallinity index than OPEFB-TCF-MCC. The TGA indicated that all MCC samples showed a higher decomposition temperature compared to pure cellulose. However, OPEFB-NaClO2-MCC showed better thermal stability than OPEFB-TCF-MCC. It was clear from SEM images that the different MCC particles had rough surfaces and micro-sized particles. Overall, results confirmed that the obtained MCC samples displayed comparable properties with those of commercial MCC. The MCC produced from OPEFB using NaClO2 is a promising material to prepare high value-added products compared to MCC produced using TCF delignification treatment.
