  Abstract

Perfluorinated sulfonated polymer(Nafion)-ethylenediamine(en)이 화학수식된 유리탄소전극으로 Fe(II) 이온의 정량에 대해 연구하였다. Fe(II) 이온의 착화제인 en을 nafion에 고정시켜 유리탄소전극 표면에 수식하면 이 수식전극의 en은 Fe(II) 이온과 [Fe(en)3]+2의 착물을 형성한다. Nafion-en이 화학수식된 유리탄소전극에서 시차펄스전압전류법에 의한 Fe(II) 이온의 산화봉우리전위는 0.340±0.015 V(vs. Ag/AgCl), 측정범위는 5?0-6∼0.2?0-3 M(0.28∼11.17 mg/L), 검출한계(3s)는 1.89?0-5M(1.056 mg/L)이었다. 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).
