Electrochemical determination of pyrogallol at conducting poly(3,4-ethylenedioxythiophene) filmmodified screen-printed carbon electrodes

Abstract
The electrochemical oxidation of pyrogallol at electrogenerated poly (3,4-ethylenedioxythiophene) (PEDOT) film-modified screen-printed carbon electrode (SPCE) was investigated. The voltammetric peak for the oxidation of pyrogallol in pH 7 buffer solution at the modified electrode occurred at 0.13 V, much lowered than the bare SPCE and preanodized SPCE. All experimental parameters, including the electropolymerization conditions and solution pH values, were optimized to improve 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.Biography
Shu-Hua Cheng completed her PhD in chemistry from National Taiwan University in 1994. After teaching in Chia Nan University of Pharmacy and Science for five years, she moved to Department of Applied Chemistry at National Chi Nan University, and promoted to full Professor in 2006. Presently her research works mainly focus on the design of conducting polymers and hybrids, and fabrication of modified electrodes for sensitive and selective determination of small molecules related to health care and environmental monitoring.
