中文摘要:

∶分光光度计法和磷钼酸喹啉容量法是测定淀粉磷酸酯取代度的常用方法．实验表明，磷钼酸喹啉容量法在数据精密度和重现性方面差于分光光度计法，且试剂配制繁琐．而分光光度计法可同时测多种未知样品，且操作方便，结果准确．

英文摘要:

In this paper the degree of substitute of starch ester phosphates was determined by phosphomoly adic acidquinoline volumetry and spectrophoto metric method.it was found that the former is less than the later in precision and reapearance. By spectrophoto
