| Abstract: | The elecoatalytic behaviors of poly (2, 5 - Dirnethayaniline ) film eletrode (PDMA/Pt ) on quinonehydroquinone (QHQ) hav been ivestigated by cyclic voltammetry and rotaing disk electrode, the redox peak curren of QHQ at the poper film elecdrie is tens times greater than those at bare Pt electrode in 1 moL. L-1 HCl: solution. The difference between the redox peak Potentials at the PDMA/Pt electrode becomes obviously less than those at the bare Pt electrode, some important factors which affect electrocalytic reaction of QHQ at the PDMA/Pt electrode were discussed. The PDMA/Pt was vety stable, it can be used as a sensor for determining QHQ. The electrode Process at the Polymer film is a diffusion controlled one in the wide range of potental sweep rate. |
