The present work elucidates, for the first time, the electrochemical behavior of some of the most relevant endocrine-disrupting phenols using unmodified carbon screen-printed electrodes (SPEs). The electrochemical reversibility and mass-transport mechanism of phenol (PHOH), pentachlorophenol (PCP), 4-tert octylphenol (OP) and bisphenol A (BPA) were studied with cyclic voltammetry (CV) and linear sweep voltammetry (LSV), respectively. Subsequently, the electrochemical oxidation of the aforementioned phenols is revealed for the entire pH range (from 2 to 12) using a Britton Robinson (BR) buffer via square wave voltammetry (SWV). Furthermore, the stability of the redox behavior of the four different phenols is investigated at their optimal pH (pH=12) over time. Calibration curves exhibit a linear range between 5 and 50 µM with excellent peak potential (E_p) and peak current (I_p) reproducibility (RSD_PHOH E_p = 0.69% and RSD_PHOH I_p = 2.36%, RSD_PCP E_p = 0.49% and RSD_PCP I_p = 4.14%, RSD_OP E_p = 1.55% and RSD_OP I_p = 8.38%, and RSD_BPA E_p = 1.15% and RSD_BPA I_p = 0.31% at 10 µM, N=3) and limits of detection (LOD) of LOD_PHOH = 0.93 ± 0.02 µM, LOD_PCP = 0.92 ± 0.09 µM, LOD_OP = 0.33 ± 0.03 µM and LOD_BPA = 0.18 ± 0.01 µM. Afterwards, binary and complex mixtures of phenols were effectively analyzed in the BR buffer (pH 12) using SWV to investigate their electrochemical fingerprint. Finally, the approach was validated with real samples from a local river and compared with lab-bench standard method (high-performance liquid chromatography with a photodiode array detector (HPLC-DAD)).
