Abstract / Full Text

The surface of polycrystalline gold (Au (poly)) electrode was ex situ modified with self-assembled monolayer (SAM) of thiourea (TU) with a view of applying the electrode for the electrochemical oxidation of uric acid (UA) in alkaline media. UA undergoes an enhanced electrochemical oxidation at the monolayer of TU-modified Au (poly) (TU|Au (poly)) electrode at a remarkably lower potential with a higher current density as compared to the bare Au (poly) electrode. The enhanced activity of the electrode was achieved due to the effective blocking of harmful adsorption of UA that takes place strongly at the bare Au (poly) electrode surface. The TU|Au (poly) electrode was also found to be very effective towards simultaneous oxidations of UA, ascorbic acid (AA) and dopamine (DA) in their mixture with well separation of the peak current of the individual substance. This technique may be advantageously utilized for developing sensor for the purpose of detection of UA.
