Objective To establish a ion chromatography method for determination of phosphorus oxychloride in the air of workplace. Method The phosphorus oxychloride in the air of workplace was collected by absorb liquid and turned into hydrochloric acid, then separated in column and detected with conductivity detector, qualified by elution time and quantified by peak height or peak area. Results The linear range of phosphorus oxychloride in air of workplace was 0.72～5.76 μg/ml with its correlation coefficient 0.9999. The detecting limit of the method was 0.12 μg/ml. The smallest detecting concentration of the method was 0.08 mg/m3 for 15 L sampling air. Relative standard deviation was 3.3%～6.2% and the recovery was 97.8%～ 103.8%.The sample could be resaved at room temperature at least for seven days. Conclusion The indicators of the method correspond GBZ/T 210.4-2008<Guide for establishing occupational health standards-Part 4: Determination methods of air chemicals in workplace>. It is a good method to determine phosphorus oxychloride in the air of workplace.
