Abstrakt: In this work, a novel ratiometric electrochemical sensor for bisphenol A (BPA) detection was facilely constructed by coupling conductive carbon black (VXC-72R) with ferricyanide probe. The VXC-72R was decorated with nonionic surfactant Tween to enhance the sensitivity and coated on glassy carbon electrode (GCE), whereas K 3 [Fe(CN) 6 ] was introduced into electrolyte solution as an internal reference probe to realize dual-signal outputs. The present ratiometric electrochemical sensor achieved a highly sensitive and selective detection of BPA in PBS solution (pH = 7.0), with a linear range of 0.08-40.0 μM and detection limit of 0.05 μM. Moreover, it has been successfully applied to the determination of BPA in real lake water and milk samples with the satisfactory recoveries rates of 94.8-102.3 %.
