摘要
Electrochemical behaviours of Europium-ferrocene derivative complex chemically modified electrodes were studied in the paper. Various factors which affect the voltammetry of the thin film modified electrodes, and the charge transport process of the thin film electrode were discussed. Size of the hydrated anion (counter ion), concentration of the electrolyte, swelling property of the film in the solvent and thickness of the film have significant effects on the voltammetry of the thin film electrode. Electrochemical behaviours of europium-ferrocene derivative compelx chemically modified electrode were studied in an aqueous solution. When scan ning between 0-0.8 V (vs. SCE), experimental results indicate that the chemically modified electrode has good stability and reproducibility. The apparent rate constant of electrode reaction is deteminedd to be 6.7×10-1 s-1.
