摘　　要：目的：探讨一次采样用离子色谱法同时测定工作场所空气中有毒物质HF、HCl、H2SO4的含量。方法：以多孔玻板吸收管采样，离子色谱法测定。结果：方法采样效率〉92％，方法的检测限HF0．02mg／L，HCl 0．12mg／L，H2SO4 0．14mg／L，精密度试验均小于10％。回收率92．6％-105．8％。结论：本法灵敏度高，选择性好，操作简单。方法的线性范围、检出限、采样效率、准确度和精密度均符合方法学要求，且一次采样可同时分析工作场所空气中HF、HCl、H2SO4浓度，此法适用于职业卫生日常监测要求。Objective：To develop a method for determination of HF, HCl and H2SO4 in workplace air. Methods： Samples were detected by ion chromatography （IC） after being collected with multi-hole absorbing tubes. Results：The efficiency of sample collecting was high（〉92% ）. The detection limit of HF was 0.02 mg/L,HCl was 0. 12 mg/L,H2SO4 was 0.14 mg/L. The RSD was less than 10%. The rate of recovery was 92.6%-105.8%. Conclusion：The method is sensitive, selective and simple for the determination of HF, HCl and H2SO4 in workplace air. The linear range of detection limit, efficiency, accuracy and precision re- quirements are in line with methodology. The law applies to monitoring day-to-day requirement of the occupational health.
