 Abstract
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 . The oxidation peak potential by differential pulse voltammetry(DPV) was observed at 0.3400.015 V(vs. Ag/AgCl). The linear calibration curve was obtained in iron(II) ion concentration range , and the detection limit(3s) was M(1.056 mg/L).
