Z Zhang,Y Lu,

In this paper the method used for the determination of F-, Cl-, No3- and SO(4)2- in the total suspended particles in air (TSP) by ion chromatography was established. The contrast between the blank values of filter membranes of ultra-thin glass fiber and chlorinated PVC, the contrast between extraction methods by supersonic extraction with 70 degrees C water and by just stand for 24 h, and the contrast between extraction solutions with deionized water and the eluent (2.2 mmol/L Na2CO3-2.8 mmol/L NaHCO3) were involved. The determination of the uniformity of filter membrane and the typical samples were also carried out. This paper adopted ethylene tetrachloride filter membrane, deionized water and supersonic for extraction. The average recoveries of this method for F-, Cl-, NO3- and SO(4)2- were 98.7%, 103%, 101% and 99.8% respectively and the RSD's were 0.29%, 0.32%, 0.30% and 0.25% respectively. This method possesses better recovery and precision.
