| 摘 要： | 以室温离子液体——四氟硼酸正丁基吡啶（BPBF4）为溶剂，在293．15K-343．15K温度范围内，测定了浓度为0.07170mol／kg的FeCl3的伏安曲线，确定了Fe^3＋的还原是扩散控制的单电子转移可逆过程，用计时电流法估算了在不同浓度和不同温度下Fe^3＋的扩散系数D，进而求得了它在不同浓度下的扩散活化能。

| Abstract: | The chronoampermetry for various molality 0.07170 mol/ kg of FeCl_3 in the ionic liquid, BPBF_4, at GC working electrode referred to Al/Al~ 3+ by different scan rates were measured over temperature range of 293.15 to 343.15 K. Since the Fe~ 3+ reduction reaction is a reversible process with one transfer electron, according to Cottrell's equation, values of diffusion coefficient of Fe~ 3+ at different temperatures were estimated. And in term of Arrenius' equation, values of its diffusion activation energy for various concentrations of Fe~ 3+ were obtained. As temperature increases, values of the diffusion coefficient also increase owing to the diminution of the BPBF_4 viscosity. |
