为了充分地利用甘蔗皮资源,提高其应用价值,本文以紫皮甘蔗为研究对象,采用X射线技术对其不同部位的成分、微纤丝角和相对结晶度进行了研究。结果表明:紫皮甘蔗的硬质皮层的主要成分是C、O和少量的N、Si、Ca等元素。从底部到末梢,微量的N、Si、Ca等元素的含量逐渐减少,从底部向顶部O/C比先减小后增大。皮层纤维素的结晶度在34.02%~41.05%之间,平均值为35.49%,自下而上呈减小趋势;皮层纤维素的微纤丝角在48.00?到68.08?之间,平均值为52.23?,从底部到顶部呈先减小后增大的变化趋势。

In this study, Both X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were applied in analysis of sugarcane rind along the height of its stem. Results showed that the main two components of the purple sugarcane rind are C, O, and a small amount of N, Si and Ca. From the bottom to the top, content of N, Si and Ca become lower. The atomic ratios of oxygen to carbon increase at first and then decrease from the bottom to the upward. The crystallinity of cellulose between 34.02% and 41.05% shows a trend of decrease along the stem. Microfibril angle is between 48.00? and 68.08?, and its change trend decreases firstly and then increases.
