DETERMINING REACTION POTENTIALS AND KINETIC CURRENTS OF DDT DERIVATIVES REDUCTION ON CV POLARIZATION CURVES

Abstract

    Electrochemical method for the DDT decomposition has been recently interested due to its simplicity and disponibility. In previous paper, the cyclic voltammetry (CV) technique has been examined and reliably considered as suitable and strong electrochemical method for studying DDT reduction in solvent electrolyte C2H5OH + CaCl2. In this paper the principal thermodynamical data of the DDT decomposition, such as reaction potential Epu, wave half potential E1/2, kinetic wave half current J1/2 and limited current Jgh are determined using differential technique applied directly on the polarization curve with regard to CV cycle numbers. The accuracy and reliability of the parameters determination are controlled by technical differentiation with attention to the concentration of reactants.

Keywords: Inseticide DDT, Cyclic Voltammetry (CV), differential of CV curve, reaction data.
