The electrochemical behavior of ascorbic acid (AA) is studied by means of cyclic voltammetry (CVA) and square-wave voltammetry (SWVA) on a boron doped diamond electrode (BDD). The possibility of using the voltammetric response signal to determine quantitatively the concentration of AA in an aqueous solution is shown. An analytical direct correlation function for SWVA at BDD is obtained. It is shown that the detection limit for AA is 1.87 μM. The applicability of SWVA for determining the content of AA in pharmaceutical preparations is demonstrated.
