【 摘 要 】

Determination of iron(II) ion with a perfluorinated sulfonated polymer(nafion)-ethylenediamine(en) modified glassy carbon electrode was studied. It was based on the chemical reactivity of an immobilized layer(nafion-en) to yield complex [Fe(en)3]+2. The oxidation peak potential by differential pulse voltammetry(DPV) was observed at 0.340?.015 V(vs. Ag/AgCl). The linear calibration curve was obtained in iron(II) ion concentration range 5?0-6~0.2 10-3M(0.28~11.17 mg/L), and the detection limit(3s) was 1.89?0-5M(1.056 mg/L).
