Determination of Mercury (II) Ion on Aryl Amide-Type Podand-Modified Glassy Carbon Electrode

Figure 1

Cyclic voltammograms of blank solution (solid line) and 5 × 10⁻⁷ moL L⁻¹ of Hg²⁺ at AAP modified GC electrode (dashed line). Electrolyte: 0.1 mol L⁻¹ HAc + 0.1 mol L⁻¹ NaCl (pH 7.0) solution. Deposition time (𝑡_d): 12 min.; deposition potential (𝐸_d): −0.8 V; scan rate (v): 50 mV/s. GC electrode modified with 0.125 μmoL AAP.
