Abstract
AbstractGraphene nanosheets modified glassy carbon electrode (GNs/GCE) was fabricated as voltammetric sensor for rutin with good sensitivity, selectivity and reproducibility. The sensor exhibits an adsorption‐controlled, reversible two‐proton and two electron transfer reaction for the oxidation of rutin with a peak‐to‐peak separation (ΔEp) of 26 mV as revealed by cyclic voltammetry. Moreover, the redox peak current increased about 14 times than that on bare glassy carbon electrode (GCE). The linear response of the sensor is from 1×10−7 to 1×10−5 M with a detection limit of 2.1 × 10−8 M (S/N = 3). The method was successfully applied to determine rutin in tablets with satisfied recovery.
