Figure 5. (A) Chronoamperometric responses of the CuO/AgO-based sensor integrated in the flow system, recorded in 0 to 496 mg L solutions. In order to record these signals, potential was shifted from +150 to +750 mV vs gold pseudoreference.
(B) Calibration curve of the CuO/ AgO-based sensor in the flow system. Standard deviation of three measurements carried out consecutively is given in brackets and drawn as error bars.
