(a) Differential pulse and (b) square wave voltammetry and of 1.0 × 10⁻⁵ M FXN in 0.2 M phosphate buffer solutions at different pH on GCE. Insets: versus pH plots. DPV conditions were pulse amplitude, 50 mV; pulse width, 50 ms; and scan rate, 20 mV s⁻¹ and SWV conditions were pulse amplitude, 25 mV; frequency, 15 Hz; and potential step, 4 mV.
