| Summary: | Hydrodynamically modulated rotating disk electrodes (HMRDE) have been studied and utilized with a basic system. Experimental results follow the theoretical predictions fairly closely with a few exceptions. HMRDE is useful in reducing complications due to background currents. The goal of HMRDE in this report is separation of currents due to surface responses from diffusion controlled currents. Some measure of success was obtained by incorporation of Ru(NH_3)^(3+)_6 into a Nafion film. However, the sine wave and square wave modulations are cumbersome and highly inefficient. Once the rotator is interfaced to the IBM 90004 for experimental control and data collection, separation of surface response using HMRDE will be feasible on a practical time scale. |
