摘要
本文用分光光度法和电势法研究了酒石酸（以TA表示）—BrO<sub>3</sub><sup>-</sup>—H<sub>2</sub>SO<sub>4</sub>——丙酮（以Act表示）体系在Mn<sup>2+</sup>催化作用下的振荡反应,探讨了许多因素对振荡反应的影响,根据实验结果和振荡反应的一般机理,对上述体系振荡反应的机理作了探索并用于解释实验现象。获得了振荡反应参数与反应物浓度之间的两个关系式。
In this paper ,a chemical oscillating system of tartaric acid-KBrO3-H2SO4-acetone in the presence of Mn2+as catalyst has been studied. The effects of many factors on the oscillation have been investigated. According to the experimental results and the general oscillating mechanism,the mechanism of this system has been proposed. It can explain the oscillating features successfully. Based on the experiments,the following relationship can be obtained. tin∞[H2SO4]0-0.89 • [BrO3-]00.79 • [Mn2+]0-0.59 • [TA]0-0.59 • [Act]0-0.87 tp∞[H2SO4]0-1.11 • [BrO3-]00.98 • [Mn2+]00.53• f[TA]0• [Act]00.60
