NO Measurements in Atmospheric Corrosion Studies


Recent trends of higher energy consumption, along with new combustion technologies and drastic reduction of SO2 emissions, have led to an increased relevance of the effect of other atmospheric pollutants on material stability. As a significant constituent of this group of new contaminants, nitrogen oxides have been considered as the cause of several atmospheric corrosion problems. Consequently, measurement of the content of NO2 in the atmosphere has become important. Looking for an easy analytical procedure to aid in conventional atmospheric corrosion studies, a technique based on the diffusion tube principles is introduced in this work. The results show good promise. Theoretical considerations, experimental results, their analysis and conclusions are included here, as a contribution to a better understanding of the atmospheric corrosion phenomena.
