Measurment Methods Comparison of Diffusion Coefficient for Fe(CN )_6￣(3-) /Fe (CN )_6￣(4-) System

本文用循环伏安法、计时电位法、计时电流法、计时电量法和旋转圆盘电极研究了Ｆｅ（ＣＮ）_６^（３－）／Ｆｅ（ＣＮ）_６^（４－）体系的电化学反应过程，用上述几种电化学方法测定了Ｆｅ（ＣＮ）_６^（３－）／Ｆｅ（ＣＮ）_６^（４－）离子的扩散系数，对测定的方法和结果作了全面的分析比较．

The electrochemical reaction processes of Fe (CN )_6(3-)/Fe (CN )_6(4-) system were studiedwith cyclic voltammetry, chronoamperometry, chronopotentiometry, chronocoulometry,rotating disk electrode and the diffusion coefficients for the system were determined. Thepaper also made a comprehensive analysis of measurment methods and measuring results.
