综合分析法鉴别新型纤维

Identification of New Type Fibres by Comprehensive Methods

采用显微镜法、燃烧法、红外光谱法相结合的方法,确定了一种未知的由纤维素和海藻酸两部分组成的新型纤维,并且通过对各组分性质的分析,最终采用化学溶解法确定了海藻酸的含量在3%～8%之间,与实际情况相吻合。

By combination use of the microscope, dombustion, and IR spectrometry, we determine the contents of an unknown fibre, i.e., cellulose and alginate; then by the dissolve method, we finally calculate the quantity of alginate.
