Application of Fourier Transform in Current Separation of Fast Scanning Voltammetry / 分析化学

ABSTRACT

A mathematical model of electro-chemical cell was induced according to its electric model. Based on the mathematical model, Fourier transform (FT) was applied to separate the charging current from Faradaic current in fast scanning voltammetric signal. The proposed method was investigated with both simulated voltammogram and experimental voltammogram. The results indicate that the proposed methods can successfully separate the charging current from Fradaic current, and the result is consistent with theoretical model.
