Electrodes Modification Based on Metal-Free Phthalocyanine: Example of Electrochemical Sensors for the Detection of Acetic Acid

Figure 3

CV curves of Au SPE-PcH₂tBu with addition of the acetic acid. Scan rate = 0.1 V/s. Inset represents the calibration curves obtained from the anodic peak current as function of the concentration. Note that the curve for the AA 0.3 M is only represented here to point the saturation phenomenon.
