Abstract

A rapid,simple and accurate method for the determination of various anions in acid rain by ion chromatography was developed.The pollution status in the campus was investigated on the scene.The results showed that the concentration of F-was above the standard level in a few areas,while the concentration of SO24,Cl-,NO-3 and F-was below the standard level in most areas.The limits of detection(LOD) were 0.02mg·L-1 for F-,0.04mg·mL-1 for Cl-,0.07mg·L-1 for NO-3 and 0.09mg·L-1 for SO2-4.The recoveries were from 96.4% to103.4%.This developed method can be used for the analysis of usual anions.
