Kinetics and Mechanism of Electron Transfer to Heptavalent Manganese by DL-Aspartic Acid in Alkaline Aqueous and Micellar Media

Table 1

Effect of [DL-Aspartic acid], [MnO₄⁻], and [OH⁻] on the oxidation of DL-Aspartic acid by permanganate in aqueous alkaline medium at 298 K. [MnO₄⁻] = 2.0 × 10⁻⁴ mol dm⁻³ and I = 0.05 mol dm⁻³.
