Abstract：The elemental analyzer was used innovatively to analyze the total nitrogen content in atmospheric aerosol, the total organic carbon and ion chromatography were used to determine water-soluble total nitrogen and water-soluble inorganic nitrogen content respectively. Otherwise, the water-soluble organic nitrogen and insoluble total nitrogen based on the estimated subtracting methods were also obtained. The analysis results of the application example of PM2.5in Xi'an demonstrated that these nitrogen analytical methods and the estimated subtracting method are accuracy and strong operability.
Keywords：atmospheric aerosol; fine particulate matter (PM2.5) ; nitrogen deposition; elemental analysis
