本文从实验上探讨了空气等离子体出气中的五氧化二氮(N2O5气体)通过硝酸盐的生成和液态硝化过程对出气液中液态水的影响。在pH=11时,N2O5气体的生成被与对羟基苯乙酸酯(p-HPA)的竞争反应抑制约50%。这表明N2O5气体衍生的中间物种在近地表生成,进而转化为。研究还发现,用NiSPY-3N观察到的硝化反应速率可以是生成速率的数量级。根据对空气等离子体流出气体和液态物种的实验结果,N2O5气体暴露在液体表面的作用被解释为提供给液体表面的中间物种,如溶剂化的硝离子()。由此推断出的N2O5气体的作用有助于发展和理解与N2O5气体有关的等离子体生物应用。
This paper experimentally discusses roles of dinitrogen pentoxide (N 2 O 5gas) in the air plasma effluent gas on the effluent gas exposed liquid water, through nitrate () generation and nitration processes in the liquid phase. The generation from N 2 O 5gas is suppressed approximately up to 50% by a competing reaction with a p-hydroxyl-phenyl-acetate (p-HPA) at pH= 11. This indicates a near-surface generation of an intermediate species derived from N 2 O 5gas, which turns to. Also, it is found that the nitration reaction rate observed with NiSPY-3N can be of the order of the generation rate. From experimental results on the air plasma effluent gas and the liquid phase species, the role of the N 2 O 5gas exposure to the liquid surface is interpreted as an intermediate species supply to the liquid surface, such as the solvated nitronium ion (). This deduced roles of N 2 O 5gas can contribute to developments and understanding of the N 2 O 5gas-involved plasma biological applications.
