摘要:
Two new carbon film electrodes have been prepared from the low pressure pyrolysis of aromatic anhydrides onto quartz substrates. The anhydrides employed are safer and more volatile than those previously used for preparing carbon film electrodes. The voltammetric response of the film electrodes both in millimolar dopamine and in background electrolyte was studied. The differential pulse voltammetry response with a mixture of dopamine, homovanillic acid and ascorbic acid was studied. Also, the application of the electrode as an optically transparent carbon electrode was examined. The film electrodes had lower background current than glassy carbon, but the reversibility with dopamine was not ideal. These two new films appear to have utility similar to previously studied films, with the advantage of rapid and safe production.
