Abstract

The electrochemical oxidation of 1, 3, 7-trimethyluric acid has been studied in phosphate buffers in the pH range 2.1—10.2 at solid electrodes. In cyclic voltammetry a single, well defined, pH-dependent oxidation peak was obtained at all of the three electrodes used. However, the reduction behavior of the oxidation product was different at pyrolytic graphite, glassy carbon (GCE), and platinum due to adsorption at PGE and GCE. The nature of the ...
