| Abstract: | Anew chemiluminescence method for the determination of trace nitrite based on its oxidation of K4Fe(CN)6 is studied. The chemiluminescence signal arises from the reaction of luminol-K3Fe(CN)6.The detection limit is 3.6×10-9g/mLfor nitrite, the calibration curve is rectilinear from 1×10-8 to 6×10-6g/mLof nitrite, and the relative standard deviation is 3.2%, This method has been applied to the analysis of natural waters, saliva and foods with satisfactory results. |
