Monitoring of Gaseous Pollutants

The air besides containing gaseous pollutants like S02, NOx, CO, HC also contains particulate matter which is made up of complex organic compounds, inorganic elements, and their oxides and secondary particulates. In view of possible large social, economic, ecological, and aesthetic value, it has become important to analyze these pollutants in the ambient air. Different analytical techniques are available for the analysis of anions. This chapter focuses on Ion Chromatography (IC), which is the only instrumental technique that can be used for rapid, sequential analysis of different anions simultaneously.
