ABSTRACT

The study investigated the reactive dissolution of gas phase nitrogen-oxides and ozone in water. Mixtures with variable composition of nitrogen oxides were produced by mixing nitric oxide (NO) with ozone. Pure NO in Ar carrier gas resulted in the production of NO₂⁻ but its production rate was limited by low NO solubility. The presence of NO₂ in the gas increased the production of NO₂⁻ while NO₃⁻ was also produced. The presence of N₂O₅ in the gas abruptly increased the production of NO₃⁻ due to higher solubility of N₂O₅. In the present configuration, about 8% of NO₂ was dissolved in the water while for N₂O₅ the fraction was 78%.

摘要

该研究调查了气相氮氧化物和臭氧在水中的反应性溶解。通过将一氧化氮（NO）与臭氧混合来生产具有可变氮氧化物组成的混合物。Ar载气中的纯NO导致产生NO _2- ^，但其生产率受到NO溶解度低的限制。NO的存在₂的气体中增加NO的产生₂ ^-而NO ₃ ^-也被制备。N的存在₂ ø ₅的气体中NO的产生突然增加₃ ^-由于N个较高的溶解度₂ ö ₅。在本构造中，约8％的NO ₂溶解在水中，而对于N ₂ O _5，该比例为78％。
