SWASV measurements for GC/Nafion and GC/silica/Nafion electrodes in 4 μM Cd(II) solution at pH 6 (A) and 4.4 (B). Experimental conditions: electrolyte, 0.1 M phosphate buffer; starting potential, −1.3 V vs Ag/AgCl, KClsat; frequency, 25 Hz; amplitude, 0.005 V; step potential, 0.004 V; deposition potential −1.3 V vs Ag/AgCl, KClsat; deposition time, 120 s; equilibration, 10 s; electrode conditioning, 0 V vs Ag/AgCl, KClsat; duration, 60 s, deoxygenation using Ar for 5 min before measurements and 30 s between each measurement.
