Studies of ascorbic acid electroactivity in the H2O/ACN(EtOH) solutions containing SDS

► Ascorbic acid (AA) activity as an antioxidant agent in various solutions. ► Data obtained from water and mixed water/ethanol, water/acetonitrile systems. ► AA electrooxidation depends on pH of the background solution. ► Anionic surfactant in solution changes peak potential and peak current. ► In organic solvent influence of surfactant on AA electrooxidation decreases.
