Determination of Nitrogen Oxide in Ambient Air by Using Ion Chromatography
ZHANG Ya-peng;Dafeng District Environmental monitoring station;
For the simple and rapid determination of nitrogen oxide in air,the method using 5% hydrogen peroxide solution as the absorption solution to collect air samples was established,so that all nitrogen oxides in air samples were converted to nitrate to be determined by ion chromatography. This method was simple,fast,precisive and accurate,which could be used to avoid the use of chemical solvents,and had no second pollution to the environment. It was suitable for the determination of nitrogen oxides in ambient air.
