Electrochemical Behavior and Sensitive Detection of Rutin on Graphene Modified Electrode
摘要
Abstract
The aim was to study the electrochemical behavior of rutin on the graphene modified electrode and develop the corresponding detection method.[Method] Amino functionalized graphene was prepared with a chemical reduction method and was used to fabricate the sensitive rutin electrochemical sensor.Cycle voltammetry and difference pulse method were used to study electrochemical behavior of rutin on modified electrode,and difference pulse voltammetry was adopted to determine rutin.[Result] Due to the high special surface area and electrical conductivity of graphene,rutin exhibited an enhanced electrochemical activity in the novel sensor.The study of electrode reaction kinetics indicated that rutin undr went a surface-controlled quasi-reversible process.Under the optimized experimental condition,the fabricated sensor displayed excellent analytical performance for rutin detection from 2.0 × 10-8 to 1.0 × 10-5 mol/L with a low detection limit of 1.0 × 10-8 mol/L at 3σ.[Conclusion] The proposed electrochemical sensor exhibited good selectivity and stability,and it could be used for real samples.关键词
