The importance of Ascorbic acid (vitamin C) in several biological processes, and during the last years as active compounds used in several pesticides (L-Ascorbic acid is used as a fungicide on glasshouse tomato, potato, and field and glasshouse flower bulbs) is a challenge for groups of researchers to develop new, rapid and sensitive method for its detection. Methods for the detection of Ascorbic acid (AA) were developed and optimised using differential pulse voltammetry (DPV) analysis with modified carbon-printed electrodes with cobalt phthalocyanine. There was studied detection of Ascorbic acid in hydrochloric acid 2% as supporting media. Results showed that the method developed for Ascorbic acid analyses can be used to assay different samples as teas and plant food supplements containing different botanicals.
