| 中文摘要 | the theoretical model[17] of an ultramicroelectrode modified with a redox species film is used as the diagnostic tool to characterize the catalytic oxidation of ascorbic acid at carbon fiber ultramicrodisk electrodes coated with an eastman-aq-os(bpy)(3)(2+) film. the electrocatalytic behavior of ascorbic acid at the ultramicroelectrode modified by an eastman-aq polymer containing tris(2,2'-bipyridine) osmium(iii/ii) as mediators is described. in order to determine the five characteristic currents quantitatively, the radius of the ultramicroelectrode and the concentration of ascorbic acid are varied systematically. the kinetic zone diagram has been used to study the electrocatalytic system. this system with 0.5-2.75 mm ascorbic acid belongs to sr + e case, and the concentration profiles of the catalyst in the film are given in detail. finally, optimizing the design of catalytic system is discussed. |
