Biobased waste utilization is an intriguing area of research and an ecologically conscious approach. Plant-based materials can be used to render cellulose, which is an eco-friendly material that can be used in numerous aspects. In the current investigation, cellulose was extracted from the leaves of the Vachellia nilotica plant via acid hydrolysis. The application of this research is specifically directed toward the utilization of undesirable plant sources. To validate the extracted cellulose, FT-IR spectroscopy was applied. The cellulose was measured to have a density of 1.234 g/cm. The crystallinity index (58.93%) and crystallinity size (11.56 nm) of cellulose are evaluated using X-ray diffraction spectroscopy analysis. The highest degradation temperature (320.8°C) was observed using thermogravimetry and differential scanning calorimetry curve analysis. The analysis of particle size was conducted utilizing images captured by scanning electron microscopy. Particle size of less than 30 μm was found and they exhibit non-uniform orientation. Additionally, atomic force microscopy analysis shows an improved average surface roughness (Ra), which increases the possibility of using extracted cellulose as reinforcement in biofilms.
生物基废物利用是一个引人入胜的研究领域，也是一种具有生态意识的方法。植物基材料可用于制造纤维素，这是一种环保材料，可用于许多方面。在目前的研究中，通过酸水解从 Vachellia nilotica 植物的叶子中提取纤维素。本研究的应用特别针对利用不良植物资源。为了验证提取的纤维素，应用了傅里叶变换红外光谱（FT-IR spectroscopy）。使用 X 射线衍射光谱分析评估纤维素的密度为 1.234g/cm3、结晶度指数（58.93%）和结晶度尺寸（11.56nm）。使用热重分析和差示扫描量热曲线分析观察到最高降解温度（320.8°C）。使用扫描电子显微镜拍摄的图像进行颗粒尺寸分析。发现颗粒尺寸小于 30μm，并且它们表现出非均匀的取向。此外，原子力显微镜分析显示出改进的平均表面粗糙度（Ra），这增加了提取纤维素作为生物膜增强材料的可能性。
