摘要
大气中氮氧化物的测定实验是环境工程专业大气监测实验项目中重要的内容之一。其中在大气采样过程中用到固体试剂三氧化铬(CrO3)作氧化剂,将空气中的一氧化氮(NO)氧化成二氧化氮(NO2),而三氧化铬试剂具有毒性可对环境造成二次污染,国家有严格的控制标准。研究用一种试剂替代三氧化铬,实验测试结果相当,无毒无副作用,操作简便,解决了该实验过程中对环境造成的二次污染问题。
The experiment of NOx measuring in atmosphere is an impofrtant item in atmosphere monitoring for environmental engineering. In this experiment, solid CrO3 is used as an oxidant to oxidize NO to NO2, however, CrO3 is toxic to the environment. So researching a new reagent to replace CrO3 is very useful, for this purpose a new test was done and had obtained a good effect. Moreover, the manipulation of the experiment is easy and without pollution and toxic byproduct.
