Poly(2‐aminophenol) films were electrochemically prepared on Pt electrodes at a constant potential from a deoxygenated aqueous solution of monomer dissolved in 0.1 M KCl. The uric acid selectivity of polymeric electrodes prepared at the different thicknesses was examined in the presence of ascorbic acid. The results showed that the polymeric film allows penetration of large amounts of uric acid while blocking the electrochemical activity of ascorbic acid in the potential region examined when compared with that on the bare Pt electrode. The regular and repetitive responses for uric acid were obtained even in the presence of the interfering substances such as ascorbic acid, cysteine, oxalic acid, lactose, sucrose, and urea. Moreover, the stability and the reversibility of the polymeric sensor were satisfactory. Therefore, it has been claimed that the polymeric electrode could be used as uric acid‐selective membrane in the presence of the mentioned interfering species. © 2010 Wiley Periodicals, Inc.
