Laser-based instruments for measurement of gaseous nitrous acid were developed by using techniques of cavity ring-down spectroscopy and wavelength modulation spectroscopy with a continuous-wave quantum cascade laser in the mid-infrared region. The heterogeneous reactions of NO2(g) with water in the presence of 20 mM KI, 20 mM NaBr or 100 mM NaClO4 have been investigated by direct monitoring of HONO(g) in the gas phase. The formation of HONO(g) was decreased by addition of KI or NaClO4, while NaBr have little effect on the formation of HONO(g).

采用光腔衰荡光谱技术和波长调制光谱技术，研制了中红外连续量子级联激光器测量亚硝酸气体的激光仪器。在20 mM KI、20 mM NaBr或100 mM NaClO_4存在下，NO_2（g）与水的多相反应已通过直接监测气相中的HONO（g）进行了研究。KI和NaClO_4的加入降低了HONO（g）的生成，而NaBr对HONO（g）的生成影响不大。
