非理想性对B-Z反应体系时间自组织的影响

从理论和实验上研究了非理想性对B-Z反应体系时间自组织行为的影响,重点考察了加入惰性电解质对B-Z反应体系振荡周期的影响,按照Oregonator模型,通过小寄生参数法动力学理论分析表明,非理想性对B-Z反应体系振荡周期的影响体现在振荡周期与铈离子的活度系数成反比,而且惰性电解质的加入使得振荡周期进一步加长.通过一系列实验观测,原则上得到了与理论分析一致的结论.

Influence of Nonideality on Temporary Self-organization of B-Z Reaction System

The influence of nonideality on the temporary self-organization behavior of the B-Z reaction system is studied both theoretically and experimentally. The oscillatory period of the B-Z reaction system containing the additive inert electrolyte has been analyzed based on the Oregonator model. By means of the method of small parasitic parameters, it turns outthat the oscillatory period of the nonideal B-Z reaction system is in inverse proportion to the activity coefficient of Ce4+. Moreover, the additive inert electrolyte can further extend the oscillatory period. When a setofobservation experiments has also been performed, the results are in accordance with the theoretical conclusions principally.
