Square Wave Voltammetric Determination of Residues of Carbendazim Using a Fullerene/Multiwalled Carbon Nanotubes/Nafion/Coated Glassy Carbon Electrode

Figure 2

(a) Effect of the amount of fullerene/MWCNT (mg) in 2 mL of Nafion (5%) on the SWV peak current of 7.84 × 10−6 mol/L MBC. (b) Effect of Nafion concentration on the peak current of 10−5 mol/L MBC. Experimental conditions: accumulation in 0.01 mol/L acetate buffer (pH 5); striping analysis after 60 s deposition at −0.6 V, scan rate: 250 mV/s, amplitude: 0.02 V, and frequency: 25 Hz.
