Characterization of biomass based novel microcrystalline cellulose from Eucalyptus teriticornis leaf

Abstract Environmental protection is the key impetus for research into the utilisation of weeds derived from plants in this sector. Waste materials exhibit a wide range of potential uses, particularly following the recycling procedure. The study’s methodology included the leaves of eucalyptus plants growing on trees. To enhance the efficacy of cellulose extraction from waste, many chemical processes may be employed, including bleaching, neutralisation, alkalization, slow pyrolysis, and acid hydrolysis. Fourier transform spectroscopy, UV-visible spectroscopy, thermal analysis, scanning electron microscopy, atomic force microscopy (AFM), and X-ray diffraction analysis were all employed in order to obtain additional data regarding the separated cellulose. The crystalline size of the cellulose powder that was extracted was determined to be 9.81 nm, and it had a significant crystallinity index of 70.34%. When subjected to scanning electron microscopy, a spherical and abrasive surface is detected. As seen by the differential thermogram curve, the highest temperature at which deterioration takes place is 321.50 °C. The micro-sized particles, which have a diameter between 150 and 220 μm on average, are identified by using ImageJ. The extracted Eucalyptus teriticornis leaves cellulose’s density is 1.513 g/cm3. The yield percentage was exceptionally ordinary as 48.04%. Therefore, by improving its qualities, cellulose might potentially gain more viability for future uses.
