Abstract

A new carbon paste electrode modified with metals oxide nanoparticles was prepared, and used to study the electro oxidation of metals ions in solution by cyclic voltammetry (CV) method. The modified electrode displayed strong resolving function for the overlapping voltammetric response of metals into one well-defined peak. The potential difference between Epa and Epc was study and this range referred to the mechanism of CV process. The kinetic of electrode was studied at the temperature range from 15 ~ 35 °C; the data of voltamograms select the effect of temperature, scan rate and pH, which suggested the diffusion electron transfer in the redox process of metals oxidation. Diffusion coefficient was calculated from the Randles-Sevcik equation and the rate constant K.
