New approaches for electrochemical detection of ascorbic acid

Ascorbic acid, well known as vitamin C, acts as antioxidant, helping the prevention of cell damage caused by free radicals. The paper presents fast methods for detecting ascorbic acid, using differential pulse voltammetry in different designed experiments. There were studied the possibilities of detection using buffer systems with pH 5.8, 7.0, 7.4 and original transducers. Each compound was analysed specifically at the potential indicated by the maximum signal appeared during the electrochemical study. The method could be successfully applied for single compound detection in food and drug samples.
