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.
