Extraction and characterization of microcrystalline cellulose from Apocynum venetum
In this work, cellulose microcrystal has been isolated from Apocynum venetum (AV) through acid hydrolysis. In addition, the properties of microcrystalline cellulose (MCC-N) extracted from AV are compared with those of commercially available microcrystalline cellulose (MCC-C). The characterizations of MCCs are studied by X-ray diffraction, Fourier transforms infrared spectroscopy, scanning electron microscopy, thermo gravimetric analyzer, and Zeta potential. As compared to MCC-C, MCC-N unveil more crystallinity percentage, fewer impurities, and comparable thermal stability without modifying the chemical composition of the sample. Besides, SEM images demonstrate rough surface and slight aggregation of extracted MCC from AV. Extracted MCC from AV can be possibly utilized as a reinforcement in green composites or hydrophilic micro composites as well as a source for AV fibre derived nanocellulose. Moreover, MCC-N can also be used in food, cosmetics, and medical industries.
