Figure 4
SWAdS voltammograms recorded in BR buffer pH 2.5 with increasing nitrothal-isopropyl concentration (a), 2.0 × 10−7 (b), 4.0 × 10−7 (c), 6.0 × 10−7 (d), 8.0 × 10−7 (e), 1.0 × 10−6 (f), and 2.0 × 10−6 mol L−1 (g). The other experimental conditions were SW amplitude 50 mV, step potential 5 mV, frequency 200 Hz, accumulation time 45 s, and accumulation potential 0 V. Inset: corresponding calibration line.
