Abstract

Nanocellulose (NC) extraction from agricultural waste and lignocellulosic biomass residues has drawn considerable interest due to its low cost and wide availability. The environmental issues linked to nonrenewable materials have underscored the need for renewable alternatives that are biocompatible, biodegradable, and eco-friendly. This study aimed to investigate the potential of Ethiopian highland bamboo Arundinaria alpina for NC extraction by using acid hydrolysis. An experimental design incorporating response surface methodology (RSM) was applied to identify the optimal hydrolysis process parameters for NC extraction. The optimum conditions for NC extraction were a reaction time of 60 min, temperature of 40°C, and acid concentration of 61.40 wt%, with a yield of 43.15%. Bamboo and extracted NC were characterized for their chemical composition, particle size distribution, and crystallinity, using Fourier-transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), and X-ray diffraction (XRD), respectively. The resulting NC had a particle size of 79.64 nm. XRD analysis revealed the crystallinity indices of the bamboo and its corresponding NC was 44.60% and 74.07%, respectively. These results indicate that highland bamboo A. alpina is a promising lignocellulosic source for sustainable NC extraction, optimization, and industrial applications.

响应面法优化高原竹中提取纳米纤维素制备可持续生物纳米材料的工艺

从农业废弃物和木质纤维素生物质残渣中提取纳米纤维素（NC）由于其低成本和广泛可用性而引起了相当大的兴趣。与不可再生材料相关的环境问题强调了对生物相容性、可生物降解和生态友好的可再生替代品的需求。本研究旨在探讨埃塞俄比亚高原竹材Arundinaria alpina酸水解提取NC的潜力。采用响应面法（RSM）设计实验，确定了NC提取的最佳水解工艺参数。NC提取的最佳条件为反应时间60 min，温度40℃，酸浓度61.40 wt%，得率为43.15%。利用傅里叶红外光谱（FTIR）、动态光散射（DLS）和x射线衍射（XRD）对竹子和提取的NC进行了化学成分、粒度分布和结晶度的表征。所得NC的粒径为79.64 nm。XRD分析表明，竹材的结晶度指数为44.60%，相应的NC为74.07%。这些结果表明，高原竹是一种有前途的木质纤维素来源，可用于可持续的NC提取、优化和工业应用。
