A kinetic study on interaction of Cu (II) with d-2, 2-(Ethylenediimino)-di-1-butanol

Abstract:
A comprehensive kinetic study of complexation of Cu(II) with d-2,2-(Ethylenediimino)-di-1-butanol (Ethambutol) has been investigated at different temperatures in the pH range 2.01 -3.43 using Aminco Morrow Stopped Flow Spectrophotometer. Metal ion complexation may be useful to remove the toxicity of d-2, 2-(Ethylenediimino)-di-1-butanol. Kinetic results indicate that the ligand is not involved in the rate determining step which is, in fact, associated with the release of a water molecule from the shell of the metal ions prior to complexation with the ligand. The anionic form of d-2, 2-(Ethylenediimino)-di-1-butanol is more reactive and the protonated form interacts only to a small extent. The values of enthalpy of activation, entropy of activation corresponding to stepwise rate constants have been evaluated. The energy of the molecule and heat of formation were also calculated. A mechanism consistent with the kinetic data has been suggested.
