| 摘 要： | 造成大气污染的氮氧化物主要是一氧化氮和二氧化氮,氮氧化物的危害性如下:①形成光化学烟雾.②易与动物血液中血色素结合.③破坏平流层(同温层)中的臭氧层.④可生成毒性更大的硝酸或硝酸盐气溶胶,形成酸雨.大气中氮氧化物含量的确定是评价人类生存环境质量优劣的重要指标之一,而其测定方法的准确性又是至关重要的.本文通过实验同时介绍了盐酸萘乙二胺分光光度法测定大气中氮氧化物含量方法的改进.

| Abstract: | atmospheric pollution caused by nitrogen oxides is a major oxygen and nitrogen dioxide,nitrogen oxides harm as follow: The first one,the formation of photochemical smog,The second one,It's very easy to combination with the blood of animals.The third one,damaging the ozone lager in the stratospheric.The fourth one,can produce toxic greater nitric acid or nitrate aerosols,formation of acid rain.atmospheric nitrogen oxides content evaluation is to determine the quality of the human environment or one of the important indicators.And the accuracy of their measurement methods are essential.The experiment at the same time introduced by hydrochloric beta Guangdufa Yieran spectroscopic measurements of atmospheric nitrogen oxides content methods improved. |
