| Abstract: | The Dionex ICS-900 ion chromatography was used to analyze the F^-, Cl^-, NO2^-, NO3^- and SO4^2- 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, CI, NO2^-, NO3^- and SO4^2- 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. |
