초록

Anionic (sodium lauryl sulphate, NaLS) cationic (cetyl ammonium bromide, CTAB) and non-ionic (Tween-80) surfactants have been found to inhibit the rate of oxiadation L-proline and L-methionine by alkaline KMnO4. A first order dependence of rate of oxidation was observed with respect to MnO4 -. The order of reaction in substrate and alkali was found to be fractional nearby 0.65 and 0.55 in Aminoacid and OH-, respectively. An aggregation/association between MnO4 - and surfactant has been confirmed spectrophotometrically. A mechanism, involving kinetically inactive [MnO4 - surfactant] aggregate and consistent with kinetic data, has been proposed. The effect of surfactants has been discussed in terms of hydrophobic and electrostatic interactions.

The order of reaction in substrate and alkali was found to be fractional nearby 0.65 and 0.55 in Aminoacid and OH-, respectively. An aggregation/association between MnO4 - and surfactant has been confirmed spectrophotometrically. A mechanism, involving kinetically inactive [MnO4 - surfactant] aggregate and consistent with kinetic data, has been proposed.
