A rapid method was established to determine anions and organic acids in PM2.5 by ion chromatography. Anions and organic acids were separated by Thermo Fisher IonPac AS18–4μm and AG18–4μm chromatographic columns with potassium hydroxide solution as the mobile phase eluted within 5 min. The method showed a good linearity withr2 between 0.998 5 and 0.999 9. The RSDs were between 0.98% and 1.9%(n=7), the recoveries were 92.1%–107.4%. The LODs were 0.04–2.00μg/L. The method is suitable to evaluate the quality of regional atmospheric.
