Electrocatalytic oxidation activity of oxalic acid can be observed by using a multielectrolytic modified glassy carbon electrode (MMGCE). The MMGCE was fabricated by using the following electrolytic-oxidation/reduction processes. First, the functional groups containing nitrogen atoms such as amino group are introduced by the electrode oxidation of a bare glassy carbon electrode in an ammonium carbamate aqueous solution, and next, this electrode was electroreduced in sulfuric acid, and it was found that the reduction current gradually increased as the electrolysis time increased. This suggests that functional groups containing nitrogen atoms contributing the catalytic electron transfer of hydrogen ion are introduced. To observe the electrode oxidation wave of oxalic acid, the voltammmetric measurements of oxalic acid was carried out by using MMGCE in an acidic medium. The oxidation wave of oxalic acid at low potential range was appeared in the linear sweep voltammograms. The MMGCE exhibited well-defined peak of oxalic acid oxidation in acidic medium.

Platinum particles modified glassy carbon electrode（Pt/GCE）was prepared by electrochemically deposite. The electrochemica1 behaviors of nitrite on Pt/GCE were studied by cyclic voltammetry. The influence factors of electrocatalysis for nitrite oxidation on Pt/GCE were studied. The result showed that Pt/GCE has favorable electrocatalysis for nitrite. oxidation, which was effected by the amount of platinum particles and the pH of base solution
