Highly sensitive determination of bisphenol A based on MoCuSe nanoparticles decorated reduced graphene oxide modified electrode

A new nanocomposite , molybdenum copper selenide (MoCuSe) nanoparticles decorated with reduced graphene oxide (rGO), was successfully prepared by a facile hydrothermal method . The MoCuSe-rGO modified glassy carbon electrode (MoCuSe-rGO/GCE) was fabricated for the first time, which provided a large surface area and exhibited a rapid electron transport rate for the bisphenol A (BPA). The electrochemical behavior of BPA was investigated with various techniques and a new electroanalytical method was established with differential pulse voltammetry . Under optimum conditions, the proposed sensor showed an excellent electrochemical response to BPA with detection limit of 9.0 × 10 −10  mol L −1 and wider linear range of 3.0 × 10 −9  mol L −1 –1.0 × 10 −4  mol L −1 . Finally, the proposed method was applied to determine BPA in real samples with satisfactory results. This work might provide a new thought for the development of electrochemical sensors with hybrid materials.
