Structural, morphological and thermal properties of microcrystalline cellulose extracted from coconut husk fiber

In this work, chemically treated microcrystalline cellulose (MCC-C) was extracted from coconut husk fiber. order to extract hemicellulose, the sieved fiber with sodium hydroxide (NaOH) for dewaxing and acidified using chlorite (NaClO2) residual lignin (bleaching process). The obtained lignin-free then potassium (KOH). characterizations used equate MCC-C commercial grade (MCC) are solubility test, X-ray diffractogram (XRD), thermogravimetric analysis (TGA) scanning electron microscopy (SEM). XRD showed that crystallinity of MCC increased significantly by 80.15% 71.8% chemical treatments. TGA found active removal lignin-hemicelluloses thermal stability material were about 350–500°C 300–500°C. morphology confirmed there is an irregular cross-section, non-uniform surface, a large amount short microfibrils some impurities on surface findings has been successfully it can be further.
