A highly selective electrochemical method was developed for the simultaneous
determination of ascorbic acid (AA), dopamine (DA), and uric acid (UA) using sulfonazo III
film-modified on glassy carbon electrode. The modified electrode showed excellent
electrocatalytic activity toward the oxidation of AA, DA, and UA. The calibration curves were
obtained with 0.5–1300.0 μmolL− 1 AA, 0.05–470.0 μmolL− 1 DA, and 0.2–100.0 μmolL− 1
UA. Detection limits of 0.17 μmolL− 1 AA, 0.03 μmolL− 1 DA, and 0.11 μmolL− 1 UA were ...
