Abstract EN
A nafion covered carbon nanotubes-paste electrode modified with poly(mferrocenylaniline).
(Nf / p(FcAni)-CNTsPE), provides a novel voltammetric sensor for the selective determination of dopamine (DA) and uric acid (UA) in the presence of ascorbic acid (AA).
We studied the electrochemical activity of Nf / p(FcAni)-CNTsPE toward DA, UA, and AA by differential pulse voltammetry (DPV).
DA and UA anodic peaks appear at 0.30 and 0.45 V, respectively while an anodic peak for AA was not observed.
DPV oxidation peak values are linearly dependent on DA concentration over the range 1–150 μM (r 2 = 0.992) , and on UA concentration over the range 5–250μM (r2 =0.99) DA and UA detection limits are estimated to be 0.21 and 0.58 μM, respectively.
The modified electrode shows both good selectivity and reproducibility forthe selective determination of DA and UA in real samples.
Finally, the modified electrode was successfully applied for the determination of DA and UA in pharmaceutical or biological sample fluids.
