| Abstract: | The preparation method of carbon fiber cylinder microelectrode modified with overox-idized polypyrrole film and its voltammetric behaviour are described. The overoxidized polypyrrole film modified microelectrode tends to exclude the interference of ascorbic acid but selectively re-sponds to dopamine in neutral and acidic buffer solutions. |
