摘要

The electrochemical oxidation of pyrogallol at electrogenerated poly(3,4-ethylenedioxythiophene) (PEDOT) film-modified screen-printed carbon electrodes (SPCE) was investigated. The voltammetric peak for the oxidation of pyrogallol in a pH 7 buffer solution at the modified electrode occurred at 0.13 V, much lower than the bare SPCE and preanodized SPCE. The experimental parameters, including electropolymerization conditions, solution pH values and applied potentials were optimized to improve the voltammetric responses. A linear calibration plot, based on flow-injection amperometry, was obtained for 1–1000 μM pyrogallol, and a slope of 0.030 μA/μM was obtained. The detection limit (S/N=3) was 0.63 μM.
