- Abstract:
- A novel electrochemical sensor for bisphenol A (BPA) comprising a functionalized multiwalled carbon nanotube (MWCNT) and a low cost Silver nanoparticle (AgNP) modified glassy carbon electrode (GCE) has been developed. The MWCNT was functionalized with carboxylate groups by nitric acid and was characterized by FT-IR . The electrochemical characterization of the developed sensor was investigated by cyclic voltammetry. Modified electrode architectures with MWCNT and different amounts of deposited AgNP layers were tested. Under the best experimental conditions, the sensor exhibited a linear response to BPA from 70 nM to 6000 nM, with a limit of detection of 40 nM. Finally, real samples tests in drinking water were tested.
