Title: the AC impedance studies for copper ions in low concentration of acid medium
Abstract: In this paper, the process of AC impedance of copper iron at the platinum electrode in its low concentrations of medium was investigated. First, the linear voltammetry(LSV) curve on the platinum electrode for copper ions was measured in its low concentrations acid solution, which was divided into two intervals for discussion. Then, four different typical points were selected from the LSV curve (at the beginning of the curve, before its turning, turning and the end, respectively,). the AC impedance experiment was carried out, and the corresponding AC impedance Nyquist plots and Bode diagrams was plotted. Meanwhile, the AC impedance spectra was obtained based on a analysis of electrochemical reduction reaction in low copper ions concentration of solution. Finally, the equivalent circuit ofAC impedance was obtained according to data and analysis was made.
