In-Situ Construction Molecular Imprinting Electrocatalyst of Au-MoO3/Graphene for Bisphenol A Determination with Long-Term Stability

Molecular imprinting (MI) technology has been used in electrochemical analysis because of its unique selectivity and specificity. In this work, an sensor based on in-situ inorganic MI-Au-MoO3/graphene for bisphenol A (BPA) is designed, where MI-MoO3 hybridized with graphene nanosheets Au nanoparticles, BPA acted as the temple molecular. Differential pulse voltammetry (DPV) was to evaluate sensing performance MI-Au-MoO3/rGO toward determination it about 2.0 times that NI-Au-MoO3/rGO. The as-constructed presents a wide linear range from 0.01 106.04 μM low limit detection 0.003 μM. It also displays outstanding stability repeatability up 20 days, can be analyze content dust leachate plastic bottle. This offers promising strategy environment pollution food via MI technology.
