This study deals with a series of operations to isolate the micro-cellulose from the palm tree spathe sheath by using a modified chemical method to take into account the low cost and the completion speed and its characterization using X-ray diffraction technique (XRD), infrared spectroscopy (FTIR) and scanning electron microscope coupled with element analyzer (SEM/EDX). The results showed that the extraction method succeeded in obtaining very pure microscopic fibers with a width of 2–10 μm with a crystallinity index equal to 79.21%, containing the two cellulose features Iβ and II, that, the conversion ratio of the first to the second was estimated at 32, 87%.

枣椰树茎鞘纤维素的分离与表征
这项研究涉及一系列的操作,通过使用改良的化学方法从棕榈树的茎鞘分离微纤维素,以考虑到低成本和完成速度及其使用X射线衍射技术(XRD)的表征,红外光谱(FTIR)和扫描电子显微镜结合元素分析仪(SEM / EDX)。结果表明,该提取方法成功获得了宽度为2–10μm,结晶度等于79.21%的非常纯净的微观纤维,其中包含两个纤维素特征Iβ和II,即第一个到第二个的转化率。第二名估计为32%,87%。
