在连续氩离子激光的辅助作用下 ,研究了 Fe( CN) 3-6/ Fe( CN) 4-6体系在石墨电极、金电极、玻璃碳电极( GCE)上的电极反应过程。不同的电极 ,激光的功率越高 ,氧化还原峰电流 ipa和 ipc的相对变化越接近。同一种电极 ,激光对氧化和还原两个过程的影响也不一致。激光对电极表面的作用及热效应引起的溶液温度变化是影响电极反应过程的主要因素
The electrode reaction of Fe (CN) 3-6 / Fe (CN) 4-6 system on graphite electrode, gold electrode and glassy carbon electrode (GCE) was studied with the aid of continuous argon ion laser. Different electrodes, the laser power is higher, the redox peak current ipa and ipc relative changes closer. The same electrode, the laser on the oxidation and reduction of the two processes are not the same. The effect of the laser on the surface of the electrode and the change of the solution temperature caused by the thermal effect are the main factors affecting the electrode reaction process
