| Abstract: | Impedance data obtained from equivalent electrical circuit model is analyzed by various AC impedance analysis methods. Some factors are outlined. Nyquist plot has higher accuracy for calculating differential capacity and are more suitable for AC impedance data processing under the condition of no concentration polarization. Furthermore this data processing method is applied to measure differential capacity of GC electrode in acrylonitrile (AN) aqueous solution. |
