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 mu M for both analytes. The detection limit was estimated to be 0.35 mu M and 0.56 mu M for BPA and BPS, respectively. The designed voltammetric sensor was successfully applied in simultaneous estimation of BPA and BPS in food samples.
