Voltammetric sensor detection of bisphenol AP in industrial wastewater

This paper reports a new voltammetric method for detection of bisphenol AP (BPAP) with high sensitivity, which is based on a new electrochemical sensor from a three-component composite-modified glassy carbon electrode. The composite was characterised by various surface, structural and electrochemical analysis techniques, such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), Infrared Spectrum (IR), X-ray diffraction (XRD), Energy Dispersive X-Ray Spectroscopy (EDX) and Cyclic voltammograms (CV). The sensor had a well voltammetric response to BPAP, and the linear response ranges from 0.005 μM ~7 μM with the detection limits of 2 nM (S/N = 3). Finally, this system was utilised for determining BPAP in industrial wastewater using the standard addition method.
