Objective:To apply Ion chromatography of hydrogen chloride in the air of workplace workplace. Methods:IonPacAS19 chromatographic column was selected, eluent for hydroxide eluent, flow rate 1 ml/min, the injection volume 25 μ L, pool temperature conductivity detection 30℃, the column temperature 35℃, suppressors in automatic regeneration mode with 50mA currency. Results:In the 0 ~ 25.0mg/mL hydrogen chloride, the linear equation is: y=2.117x-0.036, r=0.9999, the detection limit is 0.06 μ g/mL, minimum detection concentration of 0.016mg/m3 (as 5.0L air sample). The result of recovery test showed that the average recovery of the method ranged from 97.6%to 101.6%, RSD was 1.56%~3.76%. Conclusion:This method is simple, rapid, accurate with high sensitivity and less interference which is suitable for the determination of hydrogen chloride in the air of workplace.
