摘要：

Nitrite, one of the pollutants widely found in atmosphere and sour rain, is an essential precursor in the formation of nitroamine, many of which have been shown to be potent carcinogens. Therefore, the detection of nitrite has received continued attention over the past ten years[1,2], spectrophotometry and ion-chromatography are mainly used Direct reduction of nitrite requires a very high overpotential at most of the conventional electrodes, but many transition-metal substituted heteropolytungstates have shown their electrocatalytic activities[3] and can be applied as an electrochemical detector to monitor nitrite in sour rain.
