چکیده
|
The oxidation of vanadyl ions in phosphoric acid led to the formation and well crystallization of deposit. by means of the voltammetry cyclic,we were able to show the mechanism of the formation of the electrolytic deposit by diffusion. the study of the influence of certain parameters such as the potential of electrolysis,the concentration of vanadyl ions and phosphoric acid h3po4,the scanning rates and the medium ph in particular,was realized. the irreversible behavior was shown. the charge transfer coefficient and the ion diffusion coefficient of vanadyl ions were calculated.
