摘要
本文建立了维生素Ｃ及其制剂的一阶导数差示脉冲极谱定量分析方法。在水溶液中，维生素Ｃ于－１．１０Ｖ（ｖｓＡｇ／ＡｇＣｌ）处出现一良好的一阶导数差示脉冲极谱峰，在１～１７５μｇ／ｍＬ范围内，维生素Ｃ浓度与其一阶导数差示脉冲极谱峰幅值呈非常显著的线性关系（Ｐ＜０．０１），方法简便、快速、灵敏，结果准确。
The first derivative differential pulse polarography was used for the quantitative analysis of Vitamin C and its preparations.In water solution there was a very good first derivative differential pulse polarographic peak at -1.10V( vs . Ag/AgCl).The linear relationship between concentration and first derivative differential pulse polarographic peak height (P<0 01) was obtained in the concentration range of 1～175 μg/mL for vitamin C .This method is simple,rapid and sensitive.The results are accurate.
