本文利用近稳态循环伏安法在除氧含氯离子的酸性体系中,对纯铁的阳极溶解过程进行了详尽研究。从低极化区到高极化区发现有3个不同的Tafel斜率区域。在低极化区内得到Tafel斜率为120mV/dec;随着电位升高,在低极化区与高极化区之间得到Tafel斜率为40mV/dec,在高极化区内Tafel斜率为120mV/dec;并得到3个区域内C1~-反应级数分 In this paper, the near-steady-state cyclic voltammetry in deoxidation of chloride-containing acidic system, the pure iron anode dissolution process conducted a detailed study. There are three different Tafel slope regions found from the low polarization to the high polarization. The Tafel slope was 120 mV / dec in the low-polarization region; the Tafel slope was 40 mV / dec between the low-polarization region and the high-polarization region as the potential was increased, and the Tafel slope was 120 mV in the high-polarization region / dec; and obtained C1 ~ - reaction order scores in three regions
