The Inhibitive Action Of Isoamyl Alcohol On The Autoxidation Of Sodium Sulfite By Cu(II) In Alkaline Medium

Abstract

The kinetics of the Isoamyl alcohol inhibited Cu(II) catalysed autoxidation of S(IV) in alkaline medium has been studied and based on the observed results following rate has been proposed. Rate constants and the order of reaction were calculated and the reaction was found to be pseudo- first order in all cases. The effect of pH and temperature are also discussed. The value of apparent activation (Ea) energy was calculated graphically by Arrhenius equation. On the basis of inhibition parameters, the reaction follows free radical mechanism. d[S(lV)]/dt = (k1+ k2[CuII]) [S(lV)]/(1 + B [Isoamyl alcohol])
