A method was established for determination of 5 kinds of cations and 3 kinds of organic amine in PM2.5 with ion chromatography. Separation was carried out on Thermo Fisher IonPac CS17 and CG17 chromatographic column with methyl sulfonic acid as mobile phase,gradient eluted and separated within 30 min. The method showed a good linearity (r2 was between 0.998 1 and 0.999 8) and satisfactory precision (RSD was between 0.72% and 1.9%,n=7). The LOD was 0.02–0.16μg/L,and the recoveries were between 88.6% and 95.6%. The method may be applied to evaluate atmospheric condition and serach for the source of pollutants.
