在7 μ M至3.5 mM（0.1-50 ppm氮）的浓度范围内测量含有亚硝酸钠和硝酸盐的废水溶液的204-和229-nm激发的UV共振拉曼光谱。废水中存在的其他化学物质不干扰NO2-/NO3-带的拉曼测量。我们观察到的检测限< 14 μ M（
The 204- and 229-nm excited UV resonance Raman spectra of wastewater solutions containing sodium nitrite and nitrate were measured in the concentration range 7 muM to 3.5 mM (0.1-50 ppm nitrogen). The other chemical species present in wastewater do not interfere with Raman measurements of NO2-/NO3- bands. We observe detection limits of < 14 muM (
