Ultrasensitive Detection of Ferulic Acid Using Poly(diallyldimethylammonium chloride) Functionalized Graphene-Based Electrochemical Sensor
Figure 7
CVs of PDDA-G/GCE in the presence of FA (5.86 × 10−6 M) at scan rate of 100 mV s−1 with accumulation time varying from 2 min to 30 min in pH 3.0 acetate buffer solution. Inset: the relationship between the anodic peak currents and the accumulation time.
