Sensitive and selective electrochemical detection of bisphenol A based on SBA-15 like Cu-PMO modified glassy carbon electrode

This work reports the electrochemical detection of bisphenol A (BPA) using a novel and sensitive sensor based on Cu functionalized SBA-15 like periodic mesoporous organosilica-ionic liquid composite modified glassy carbon electrode ([email protected]/IL/GCE). The structural morphology [email protected] is characterized by X-ray powder diffraction (XRD), energy dispersive analysis (EDX), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), Field emission scanning (FE-SEM), Brunauer-Emmett-Teller (BET). catalytic activity toward oxidation BPA was interrogated with cyclic voltammetry (CV) differential pulse (DPV) in phosphate buffer solution (pH 7.0) fabricated sensor. analyte carried out at neutral pH scan rate studies revealed that stable. Under optimal conditions, linear range from 5.0 nM to 2.0 µM 4.0 500 for detecting observed limit 1.5 (S/N = 3). applied detect tap seawater samples, accuracy results validated high-performance chromatography (HPLC). proposed method provides powerful tool rapid environmental samples.
