Resumo: A nanosensor was developed for hydrogen peroxide determination based on nafion/graphene oxide/silver nanoparticles/tertiary butylhydroquinone (TBHQ) modified glassy carbon electrode (N-GO/AgNPs/TBHQ/GCE). Cyclic voltammetry was used to investigate the electrochemical behavior of this modified electrode and differential pulse voltammetry was used for the reduction of H2O2. The limit of detection was 0.46 µmol L-1 and three linear calibration ranges were obtained for H2O2 determination from 1.52-9.79 µmol L-1 for first linear segment, 9.79-231.0 µmol L-1 for second linear segment and 231.0-8330.0 µmol L-1 for third linear segment. Finally, the reliability of the nanosensor was confirmed in the real sample analysis in different beverages with satisfactory results.
