Abstract

The electrochemical conversion of Fe2O3 nano-particles from the surface of carbon paste electrode was investigated by solid-phase voltammetry. Cyclic voltammetric curves of Fe2O3 nanoparticles transformations were recorded in direct current (first derivative) mode with a potential change at the speed of 80-90 mV/s in the potential range from -1.2 to +1.0 V. The dependence of the anodic peak of Fe2O3 nanoparticles on exposure time in a background electrolyte was researched and the method for identifying and quantification of solid-phase nanoparticles of Fe2O3 was developed. The results of determination were tested by a standard addition method.
