Abstract: The kinetics of oxidation of non-ionic surfactants, viz. polyoxyethylene(10)octylphenol (Triton X-100) and polyoxyethyleneglycol dodecylether (Brij-35) by potassium permangnate in aqueous H₂SO₄ medium have been investigated in temperature range 35-45C. The reactions show first order dependence of rate with respect to [MnO₄⁻]. The order of reaction in surfactant and H₂SO₄ decreases from unity at higher [surfactant] and [H₂SO₄], respectively. Probable reaction mechanism involving an intermediate between surfactant and active species of the oxidant is proposed and constants involved in the rate law have been evaluated.
