Voltammetry

INTRODUCTION

Voltammetry is the study of the current by applying the potential. This helps in the determination of the half-cell reactivity of the sample. The voltammetry was first proposed by the Jaroslav Herovsky in 1922 by the principle of polarography. The analytical advantage of the voltammetry is the sensitivity with different concentrations of the samples. The only interferences in the voltammetric measurements are dissolved oxygen and the solvent reduction. The main uses of the voltammetric measurements are the following:

  1. Used in the determination of the kinetic rates of the reactions.
  2. Used in the determination of the adsorption process on the surfaces.
  3. Used in the determination of the thermodynamic properties. ...
