Abstract

[Objective]To explore the simultaneous determination of hydrochloric acid,sulfuric acid and fluoride in workplace air by ion chromatography.[Methods]Hydrochloric acid,sulfuric acid and fluoride were adsorbed by porous glass tube and detected by ion chromatography with best instrument condition and suitable mobile phase.[Results]Determination limit of hydrochloric acid,sulfuric acid and fluoride was 0.06 mg/L,0.35 mg/L and 0.08 mg/L; the RSDs for 3 materials were all less than 4.63%; the recovery range was 95.0%~102.2%.[Conclusion]This method is simple,with high sensitivity and good precision.
