The cyclic voltammetry (CV) technique was accustomed to look into the electro oxidation of iron ions in water using a novel carbon paste electrode CPE enhanced with iron oxide nanoparticles. The revised electrode exhibited a high resolving function, allowing the overlapping voltametric response of Fe-ion to be resolved into a single well-defined peak. The voltage differential between Epa (anodic) and Epc (cathodic) was higher than 200 mV; this range is referred to as the quest-reversible mechanism. At temperatures ranging from 15 to 35 °C, the kinetics of the electrode were investigated. Voltammogram data revealed a rise in temperature, which resulted in an increase in negative shift, diffusion electron transfer in the Fe redox reaction. The Randles-Sevcik equation yielded a diffusion coefficient of 4.9 x 10-5; the rate constant K was 2.3 x 10-4; and the peak current of Fe-ion rose linearly with concentrations ranging from 1 to 5 ppm.
