被动扩散管监测空气中二氧化氮分析方法的改进

【摘要】 利用被动扩散法测定空气中的二氧化氮是最近几年许多发达国家所采用的方法。在二氧化氮(以后以NO2记)被动监测分析方法及Saltzman法的基础上,对所选用的化学试剂及试剂的用量、操作方法等方面进行了改进与研究,实验结果表明用对氨基苯磺酸取代对氨基苯磺酰胺,更具有可操作性、经济性和适用性。更多还原

【Abstract】 Passive Diffuse for determining airborne NO2 has over recent years become a prevail practice in many developed countries. This paper has dealt with how to improve, based on Passive Diffuse and Saltzman method, the accurate reagent dosage, operation procedures. The experiment result shows that substituting sulfanilic acid for sulfanilate amide is more beneficial to operability, economic efficiency and applicability.更多还原
