A simple and reliable method for electrochemical determination of nitrite based on Gd doped nano titanium dioxide (Gd-nano-TiO2) modified gold electrode was well developed in this paper. Using cyclic voltammetry, the modified electrode shows electrocatalytic activity for oxidation of nitrite in 0.10 mol×L-1 sulfuric acid solution (pH=0.70). The catalytic peak current was found to be linear with nitrite concentration in the range of 2.0´10-6 ~ 2.0´10-4 mol×L-1, with a detection limit of 1.1´10-6 mol×L-1 (S/N=3). Compared with spectrophotom...
