摘要： 铅锑电极上ＰｂＯ_２生长过程的阻抗跟踪法研究韦国林，杨鸿兴，王家荣（上海大学嘉定校区化学系，上海，２０１８００）利用交流阻抗技术研究Ｐｂ／Ｈ２ＳＯ４体系中电化学过程，通常采用某一等效电路，并对所得的多频率阻抗频谱进行拟合处理，由此获得相关电化学信息。?..

Abstract: The growth process of PbO2 formed by the oxidation of PbSO4 in the anodic film on lead-(1,3,5,7)wt%antimony electrodes was investigated with impedance tracing method of single frequency and the current-time transient method. The influence of antimony on this process was studied.The simulation curves obtained for capacity-time transients fit the experimental results very well.It has been shown that the mentioned growth process is a two-dimentional instantaneous nucleation and growth process,Antimony will inhibit the growth of PbO2 nucleus but enhance its nucleation.

Key words: Impedance tracing, Lead-antimony electrode, Lead-dioxide electrode, Electrocrystallization
