The electrocatalytic oxidation of formaldehyde on Nickel-Poly (o-toluidine) - polyvinylalcohol modified glassy carbon electrode (Ni-P(OT)-PVA/GCE) was developed. This involves in situ electropolymerization of o-toluidine at GCE, which is following to the incorporation of Ni (II) to polymeric layer by immersion of modified electrode in 1.0 M nickel sulphate solution. The general electrochemical behavior was characterized by cyclic voltammetry and chronoamperometry methods in alkaline media. The results showed that the Ni-P(OT)-PVA/GCE system exhibits a significant electrocatalytic activity towards oxidation of formaldehyde. The effects of scan rate and formaldehyde concentration on the electrocatalytic oxidation of formaldehyde were also investigated at the surface of Ni-P(OT)-PVA/GCE.

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
