摘　　要：提出利用目视外观法、燃烧观察法、化学法中的碘法、蒽酮法、醋酸 -苯胺试纸法、仪器分析法中的红外光谱法、电镜法进行含淀粉类可降解塑料的定性鉴定 ;采用分光光度法进行其中淀粉含量的定量鉴定。本文九种方法对含淀粉类可降解塑料的推广应用有积极意义。This paper suggested that the methods of visual examination, combustion watching, Iodine and acatic acid-phenylamine test strips of chemical methods, IR spectroscopy and electron microscope of instrumental analysis methods should be used for the qualitative analysis of the starch-containing degradable plastics. Spectrophotometric method should be used to determine the starch of it. Those nine methods are useful for the development and application of the starch-containing degradable plastics.
