| 摘 要： | 用离子选择电极电位法对S_2O_8~(2-)-Ⅰ~-体系反应动力学问题进行了探讨,研究了离子强度对反应速度的影响。结果表明:离子选择电极电位法可用于此体系的动力学研究,并且得到满意的结果;提出了该电极适用的浓度条件;得出生成CuI~+步骤为催化反应决定步骤的新结论;随着离子强度的增加dE/dt值增大,即反应速度加快。

| Abstract: | The reaction kinetics in S_2O_8~(2-) and I~- system and the influence of ionic strength on reaction rate were studied by ion selective electrode electric potential method. The method can be used in the study of reaction kinetics. It was shown that the formation of CuI~+ was the decisive step to deteme catalytic reaction. The reaction rate was accelerated with increaing of ionic strength. |
