摘要: Nano-gold (NG) modified glassy carbon electrodes (GCEs) were used for determination of epinephrine (EP) in the presence of high concentration ascorbic acid (AA) by cyclic voltammetry (CV).This modified electrode can not only catalytically oxidize EP and AA, but also separate the catalytic peak potentials of EP and AA by about 183.5 mV.In pH=7.0 ogisogate byffer solution, the linear range of epinephrine was 5×10⁶~1×10^-4 mol/L.
