A highly selective voltammetric method was developed for the simultaneous determination
of ascorbic acid (AA), dopamine (DA), and uric acid (UA) using Tiron polymer film modified
on glassy carbon electrode. The modified electrode separated the anodic oxidation peaks
potential of AA, DA and UA with a well-defined peak separation in the present of each other
to measure AA, DA and UA individually or simultaneously without any intermolecular effect.
The calibration curves were obtained over the range of 4.0-792.0 µmol/L AA, 0.2-45.8 ...
