This article reports the production of high crystalline cellulose from chickpea husk, for the first time. The work was carried out with an objective to utilize agricultural by-product for obtaining cellulose. Chickpea being a major legume of India, its husk was studied for cellulose extraction. The alkali treatment process for production of cellulose was optimized for obtaining highest yield. The optimum process conditions were 0.84 M NaOH, 70 °C temperature, and 2 h of extraction time with a yield of 73.08%. The extracted cellulose was characterized using chemical analysis, powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) analysis. Results showed that the cellulose content of 52.33% in husk improved to 69.79% after alkali treatment. Also, the crystallinity index of chickpea husk, which was 70.1%, increased to 89.5% after the treatment in extracted cellulose. This establishes the fact that chickpea husk has a great potential as a source for high crystalline cellulose which finds its application in material science and composite making.

本文首次报道了从鹰嘴豆壳中生产高结晶纤维素。这项工作的目的是利用农业副产品来获得纤维素。鹰嘴豆是印度的主要豆类，其壳被研究用于提取纤维素。对纤维素生产的碱处理工艺进行了优化，以获得最高的收率。最佳工艺条件为 0.84 M NaOH、70 ℃温度和 2 h 提取时间，收率为 73.08%。使用化学分析、粉末 X 射线衍射 (PXRD)、傅里叶变换红外 (FTIR) 光谱、热重分析 (TGA) 和扫描电子显微镜 (SEM) 分析对提取的纤维素进行表征。结果表明，经碱处理后，果壳中纤维素含量由52.33%提高到69.79%。还，在提取纤维素处理后，鹰嘴豆壳的结晶度指数为 70.1%，提高到 89.5%。这证实了鹰嘴豆壳作为高结晶纤维素来源的巨大潜力，可用于材料科学和复合材料制造。
