| 摘 要： | 本文考查了下Ｆｅ（Ⅲ）－Ｉ－、Ｃｒ（Ⅳ）－Ｉ－及Ｃｒ（Ⅳ）－Ｉ－Ｆｅ（Ⅱ）体系的反应曲线，证明由于Ｆｅ（Ⅱ）的引入，体系产生Ｃｒ（Ｖ）中间体并快速氧化Ｉ－；通过实验确定Ｃｒ（Ⅳ）－Ｉ－－Ｆｅ（Ⅱ）体系的化学计量关系，导出了诱导反应的机理及速率方程，并通过反应曲线的研究进一步证实了反应机理。

| Abstract: | The reaction mechanism of Cr(Ⅳ)- I- system induced by Fe(Ⅱ) was studied by spectrophotometry. It was found that under the induction of Fe(Ⅱ) and Cr(V) as an intermediate is first fomied, then it oxidizes I to i2 rapidly. The stoichiometric relationship of Cr(Ⅳ)-I-Fe(Ⅱ) reaction system was determined experimentally. Based on the experimental results a mechanism of the induced oxidation reaction was proposed and the rate equation was also derived. |
