Abstract
The capability of the suppressed conductometric detection ion chromatography (IC) was investigated for the separation and determination of inorganic anions (Fâ, Clâ, NO3â and SO42â) in standard reference materials SRM-1648 urban particulate matter following ultrasonic extraction. The effects of the cationic surfactant (SDS) and the anionic surfactant (CTAB) on ultrasonic extraction efficiency of inorganic anions from complex matrix of airborne particulate matter were investigated. The results showed that surfactant can enhance the extraction efficiency. Finally, the concentrations of inorganic anions in the atmosphere of the city of Isfahan were determined. The results showed a trend of SO42â > NO3â > Clâ > Fâ.
