Electrochemical Behavior of Iron (II) at a Nafion-1, 10-phenanthroline-modified Carbon Paste Electrode: Assessing the Correlation between Preconcentration Potential, Surface Morphology and Impedance Measurements

The electrochemical behaviour of a Nafion-1,10-phenanthroline-modified carbon paste electrode (CMCPE: Chemically Modified Carbon Paste Electrode) immersed in a supporting electrolyte 0.1 mol.L-1 acetate buffer solution (pH 4.5) containing iron(II) metal ion was investigated using cyclic voltammetry, differential-pulse voltammetry, and impedance
