摘要
目的推断出ClO2-I2-MA振荡反应体系的重要组成反应ClO2-I-的反应机理。方法采用紫外可见分光光度计检测I3-及I2的吸收峰,从而确定在不同的条件下体系中I3-及I2的浓度随时间的变化规律。结果推断出ClO2-I-的反应机理,并可以很好的解释实验现象。结论摩尔比[r(r=[I-]0/[ClO2]0)]及溶液pH值对反应都有很大影响,r的临界值为6.0,当r大于1.0时,pH值=2.0是曲线形状的转折点。
Objective： Deduce the reactive mechanism of a closed system containing an aqueous mixture of chlorine dioxide, iodide, and sulphuric acid. Methods： Use UV spectrophotometer to show absorbance of triiedide and iodine. To know the concentration of Ia - and 12 along with the reaction time in different conditions. Results： Deduce the reactive mechanism of chlorine dioxide, iodide, and sulphuric acid system, and explain the experimental phenomena. Conclusion： The molar ratio r and pH value has big influence to the chemical oscillatory reaction system. The critical value of r is 6.0. When r is bigger than 1.0, the turning point of the curve＇ s shape is pH = 2.0.
