摘要：
A square-wave voltammetric method at a hanging mercury drop electrode for quantitative determination of aconitic acid in aqueous solution is developed. Aconitic acid is an electroactive compound in acid and neutral medium. Its voltammetric response depends on the type as well as the pH of the supporting electrolyte. The optimization of experimental parameters for quantitative determination of aconitic acid was achieved. The quantitative determination of aconitic acid was carried out in 0.1 mol/L HCl as a supporting electrolyte. The effect of interferences is studied. The detection limit of aconitic acid is 0.184 mu g/mL.
