STUDYING KINETIC CURRENTS CORRELATION OF DDT DERIVATIVES REDUCTION WITH THE CONCENTRATION AND SCAN RATE IN CV TECHNIQUE

Abstract

     DDT is a persistent organic pollutants (POPs), having harmful effects to human health and the environment. Decomposition of DDT derivatives by electrochemical methods has been studied and presented in the previous articles. In this study, reduction kinetics of DDT derivatives was studied under the concentration influence and CV scan rate. On the cathodic branch of the polarized CV curve 4 reduction reactions of DDT derivatives are appeared. Kinetic current of these reactions are proportional to the square of the concentration of DDT of type J = kCC0.5 + JC0. The characteristic currents of the reduction reaction is dependent on the square root of CV polarization scan rate that J = kv0.5 + Jv0. The equation is found with good high correlations and reliability.
