Abstract:
A sensitive and rapid flow injection analytical method for the determination of ascorbic acid has been developed, based on the reaction between iodine and ascorbic acid(VC) and the reaction between iodine and starch. The linear range of VC is 0-12ppm. Recoveries of 96-110% can be obtained. The method was applied to the determination of VC in medicines and foods with satisfactory results.
