The electro-oxidation of rutin occurs at a potential about 0.4 V at the surface of Ag/NP/1B3MIBr/CPE and this value is less positive than the unmodified CPE. pH = 7.0 was selected as an optimize condition for all of electrochemical investigations in this work and for evaluating electrochemical parameters such as diffusion coefficient (5.0 × 10-6 cm2/s). At the optimized condition for rutin analysis, the differential pulse voltammetry (DPV) peak currents of rutin show a wide linear dynamic range from 0.05-320 μM with a detection limit of 10 nM. Finally, the Ag/NP/1B3MIBr/CPE was used for determination of rutin in soy samples with good selectivity and high sensitivity.}, keywords = {Rutin analysis,Ag Nanoparticles,Electrochemical food sensor,Modified electrode}, url = {http://www.ajchem-a.com/article_111668.html}, eprint = {http://www.ajchem-a.com/article_111668_deba455242f6553bbd0717234636876c.pdf} }
