Cyclic voltammograms of PET-AC/GCE in 0.1 M PBS at a scan rate of 50 mV s−1 (a) different electrolyte pHs (from 4.0 to 10.0) with 50 µM carbofuran-phenol (50 µM). Inset: plot of peak potential (Epa) vs. oxidation peak current (Ipa) vs pH. (b) Varied concentrations of carbofuran-phenol from 10 to 100 µM Inset: Plot of oxidation peak current (Ipa) vs carbofuran-phenol concentration (µM).
