The Dionex ICS-900 ion chromatography was used to analyze the F-, Cl-, NO2-, NO3-and SO42-in PM2.5. Linearity between the peak areas and concentrations of their respective water-soluble anions was found to be good in the definite ranges for the 5 ions, with the correlation coefficients (r) larger than 0.996. The relative standard deviations were less than 3.34%. The detection limits for F-, Cl-, NO2-, NO3-and SO42- were 0.0038, 0.0061, 0.0038, 0.0254 and 0.0611 mg?L-1, respectively. This method is easy to operate and the results accurate. With its fast detection abilities it is suitable for simultaneous determination of water-soluble anions in PM2.5.
