Portugal Gómez, Paula Alonso Lomillo, Mª Asunción Domínguez Renedo, Olga 2022-09 This work shows the potential of modified screen-printed carbon electrodes (SPCEs) for sensitive and selective detection of 4-ethylphenol in wine. Gold nanoparticles (AuNPs) and fullerene C60 (C60), modified sensors have been compared. pH of the supporting electrolyte, deposition time and working temperature have been optimized considering their influence in the voltammetric pulse response of 4-ethylphenol. Under the optimal conditions of measurement, the developed activated C60/SPCE (AC60/SPCE) shows the best performance, with a detection capability of 400 μg/L and 700 μg/L, when using deposition times of 14 min and 6 min, respectively (α = β = 0.05). The reproducibility of the developed sensor resulted better when a deposition time of 6 min was used (5.4 %, n = 3). The influence of different interferents on the analytical response has been studied, as well as their application in the determination of 4-ethylphenol in different wine samples. application/pdf http://hdl.handle.net/10259/7493 eng Elsevier 4-ethyphenol detection in wine by fullerene modified screen-printed carbon electrodes info:eu-repo/semantics/article TEXT RIUBU.
