Ascorbic acid is a well-known anti-oxidant, which is not formed in human’s body. Therefore, the body needs to receive it through other sources such as citrus or vitamin C pills. It is highly important to present a simple and cost-effective method to measure ascorbic acid in medical samples and citrus.
Dr. Meisam Norouzi, one of the researchers of the project, explained the various steps of the research. “In the first step, we produced the appropriate reactants including solid iodine and cetyl trimethyl ammonium iodide. Then, the appropriate compositions of the components in carbon paste electrode structure, including the type of the carbon, ratio of iodine to cetyl trimethyl ammonium iodide, and the amount of pasting oil were optimized. In the final step, we determined the suitable conditions for the measurement of ascorbic acid such as appropriate pH and the type of electrochemical method.”
Simplicity, using cheap materials and high performance are among the advantages of the presented method that can be used in the quality determination of medical products and also in the measurement of ascorbic acid in citrus.
