流动池的电化学现场ESR理论

THE THEORY ON IN-SITU ELECTROCHEMICAL ESR AT CHANNEL ELECTRODE

用隐式差分法解了EC_1和EC_2反应在流动池的电化学现场ESR测量中的稳态对流扩散方程.由计算结果提出了一个测量随后化学反应速度常数的简单方法,并讨论了该方法的测量限度及流动池参数对测量的影响.

The steady state convective diffusion equations of EC_1 and EC_2 reac- tions in the channel electrode located in ESR cavity are solved by the implicit finite difference numerical method. The relations of ESR signal intensity to the flow rate, the position of electrode in the cavity and the dimension of the channel cell are dis- cussed. A simple method for measuring chemical rate constant is presented.
