The effect of temperature on the voltammetry curve of carbon fiber microelectrode and the relationship between temperature and electrode potential were investigated, and the thermodynamic parameters of the electrode reaction were measured. The relationship between current and temperature was used to determine the activation energy E_ (al) and D_o The standard rate constant of the electrode reaction was determined by reversible reaction on the conventional electrode. The activation energy of the electrode reaction was measured by the relation between the temperature and the temperature.
