Individual and Simultaneous Electrochemical Detection of Bisphenol A and Bisphenol S in Food Samples Using Triethylenetetramine Functionalized Multi-Walled Carbon Nanotubes

Abstract In this concept, multi-walled carbon nanotubes (MWCNTs) were functionalized by triethylenetetramine (TETA-MWCNTs), and the as-synthesized TETA-MWCNT materials were utilized for the simultaneous voltammetric detection of bisphenol A (BPA) and bisphenol S (BPS). The voltammetric behaviors were tested by cyclic voltammetry (CV) and square-wave voltammetry (SWV). The high-priority experimental parameters have been carefully optimized. The designed sensor exhibited exceptional electrocatalytic activity toward the oxidation of BPA and BPS and provided two well-separate oxidation peaks enough to quantify BPA and BPS in a binary mixture. The standard curve was linear over the concentration range of 1.0–30 µM for both analytes. The detection limit was estimated to be 0.35 μM and 0.56 μM for BPA and BPS, respectively. The designed voltammetric sensor was successfully applied in simultaneous estimation of BPA and BPS in food samples..
