Sensitive Carbon Fiber Microelectrode for the Quantification of Diuron in Quality Control of a Commercialized Formulation

Figure 5

Cyclic voltammograms recorded in 0.1 M PBS containing 20 mg/L of diuron on (b) unmodified CFME and (c) p-NiTSPc-CFME. Curve (a) corresponds to the CV behaviour of p-NiTSPc-CFME in blank solution (baseline). Potential scan rate: 0.1 V/s.
