| Abstract: | A method for the determination of Iodine species in Aerosols was detection developed using IC and ICP-MS. IC was used in preliminary separation of the samples, and ICP-MS was used in the detection of Iodine species. The Dionex ICS-1000 ion chromatography coupled with AS18 analysis column and AG18 protection column was used and 40mmolfL KOH solution was used as the eluent. The detection limit of this method was 0.1 txg/L, its precision （RSD） was between 4.2% and 5.4% , and the la- beled recovery rate was between 80% and 101%. |
