膜覆盖的旋转圆盘电极用于评价电极电位阶跃变化后三种代表性溶质的转运和反应。提出了一种分析，允许从一个单一的测量扩散限制过程中的膜中的溶质传输特性的完整表征。对于部分反应受限的过程，如果从独立的实验中知道输运性质，则可以估计某些动力学常数。使用良好表征的膜，氧气和对苯二酚的反应作为扩散限制过程的例子进行了研究。葡萄糖氧化，其中有一个复杂的依赖于反应动力学的过程中，也进行了研究，并估计某些速率常数。这些结果提供了一个基础，在新型膜的传输特性。
The membrane‐covered rotated disk electrode was used to evaluate transport and reaction of three representative solutes after a step change in electrode potential. An analysis is proposed that allows complete characterization of solute transport properties in the membrane from a single measurement for diffusion‐limited processes. For partially reaction‐limited processes, certain kinetic constants can be estimated provided that transport properties are known from independent experiments. Using a well‐characterized membrane, reactions of oxygen and hydroquinone were studied as examples of diffusion‐limited processes. Glucose oxidation, a process in which there is a complex dependency on reaction kinetics, was also studied and certain rate constants estimated. These results provide a foundation for characterization of transport in novel membranes.
