Abstract
A sensitive electrochemical platform for the determination of bisphenol A (BPA) was constructed. A hybrid of MoS2 quantum dots decorated poly sodium styrene sulfonate functionalized reduced graphene oxide (MoS2 QDS@PSS-rGO) was prepared by a simple method. The hybrid was cast on a bare glassy carbon electrode (GCE) to form the MoS2 QDs@PSS-rGO/GCE. The electrochemical response of BPA on the MoS2 QDs@PSS-rGO/GCE was significantly enhanced compared to the unmodified electrode, indicating that the nanocomposite possessed an electrocatalytic effect. A novel method was established to determine BPA with a detection limit of 0.008 μM. The applicability of the prepared sensor was demonstrated to determine BPA in real samples with high recoveries.
