Abstract
The present techniques describe sensitive determination of dopamine (DA) at the surface of newly established
poly(pyrocatechol violet) modified glassy carbon electrode (poly(PCV)MGCE). The developed electrode was
characterized using electrochemical impedance spectroscopy. The modified electrode showed a synergic and
very remarkable electrocatalytic performance in sensing of DA at pH 5.0. Simultaneous determination of DA in
the presence of uric acid (UA) is validated. The modified chemical sensor was easy to fabricate, very stable and
reusable, and free of interference from UA. The practical analytical application of poly(PCV)MGCE toward the
determination of DA was successfully demonstrated.
