Nafion-EDTA가 수식된 유리탄소전극을 이용한 수은(II)의 측정
Determination of Mercury(II) Using Nafion-EDTA-Modified Glassy Carbon Electrodes
초록
Determination of mercury(II) using Nafion-EDTA-modified glassy carbon electrodes is proposed. it is based on the chemical reactivity of an immobilized modifier, Nafion-EDTA. Differential pulse voltammetry is employed, and the oxidation of complexes, at +0.43V vs. Ag/AgCl, is observed. For a 5-min preconcentration period, a linear calibration curve is obtained for mercury(II) concentrations ranging from 1.0
