The kinetics of oxidation of 2-aminoethanol and 3-amino-1-propanol by diperiodatoargentate(III) (DPA) were carried out spectrophotometrically in alkaline medium in the temperature range of 293.2-308.2 K. The reaction showed first order with respect to [DPA] and each reductant. The observed rate constant (k _obs) decreased with the increase of [IO₄ ^-] and increased with the increase of [OH^-]. Increasing ionic strength of the medium decreased the rate. Investigations of the reaction at different temperatures allowed the determination of the activation parameters for the slow step of proposed mechanism. The proposed mechanism and the derived rate laws found consistent with the observed kinetics.
