摘要: 用激光磁共振方法研究了氮氧化物与腐殖酸的反应.腐殖酸是一种重要的地表环境物质,氮氧化物是大气中主要的污染源之一,研究它们之间的反应从而了解地表环境物质与大气环境物质的相互作用,表明在一定程度上地表环境能吸收掉一些污染.NO2与胡敏酸反应被消除85%,NO2与富里酸反应被消除90%.NO与胡敏酸反应被消除30%,NO与富里酸反应被消除33%.腐殖酸在消除氮氧化物的同时也将被氧化和硝化形成有机矿物肥料,这些为使用地表环境物质治理工业污染废气提供了有用的数据.

Abstract: Nitrogen oxide reaction with humic substance was studied by using laser magnetic resonance. Humic substance is an important earth surfacc substance. Nitrogen oxide is one of mian pollutants.Studying their reaction lets tls know the earth surface substance interacting with atmospheric substance. The earth surface enviroment can eliminate pollution itself in some extent. 85% of NO2 disappeared due to the reaction of NO2 with humic acid. 90% of NO2 disappeared due to the reactronof NO2 with fulvic acid. 30% of NO was disappears during the reaction of NO with humic aicd. 33% of NO disappears when NO reacted with fulvic acid, at the same time humic substance is oxidized and nitrified, yielding organic-mineral fertilizer. This data is useful for dealing with industrial waste gases.

Key words: Nitrogen oxide, Humic substance, LMR
