| 摘 要： | 本文对紫外导数光谱法直接测定抗坏血酸含量进行了研究,并将该法应用于蔬菜、水果及抗坏血酸片剂中抗坏血酸含量的测定,结果表明,抗坏血酸的1—4阶导数光谱都可用于样品中抗坏血酸含量的测定,其中以二阶导数光谱的测定效果最佳。该法简便、快速、线性范围宽、准确性高,选择性好。

| Abstract: | This paper reports a method for direct determination of ascorbic acid by ultra-violet differential spectrometry and its application to analysis of ascorbic acid contents in vegetables, fruits and tablets. All the four (1st to 4th) derivatives of spectrometry were available for determination, and the better results were obtained from the 2nd derivative spectrometry. The results showed that this method was simple, rapid and accurate. |
