Abstract
Section titled “Abstract”An unmodified boron-doped diamond electrode was used for the voltammetric determination of ascorbic acid (AA). The measurements were carried out in an acetate buffer solution of pH = 4.6 by differential pulse voltammetry (DPV). Under the optimized experimental conditions, AA gaves linear response in a broad concentration range from 5 · 10-7 to 2· 10-3 mol/dm3. The detection limit was 1.63 · 10-7 mol/dm3. The proposed procedure was applied for simple and fast voltammetric determination of ascorbic acid in human urine samples and commercially available dietary supplements.
