【摘要】 目的探讨一次采样同时测定工作场所空气中氯化氢和硫酸的方法。方法以多孔玻板吸收管采样,离子色谱法测定,选定最佳测定条件,确定适宜的流动相,测定氯化氢和硫酸的含量。结果方法氯化氢的定量下限为0.028mg/m3,相对标准偏差(RSD)为2.0%～3.8%;硫酸的定量下限为0.032mg/m3,RSD为1.3%～4.2%。该法与化学法相比测定结果差异无统计学意义。结论该方法操作简便,灵敏度高,精密度好,无污染。更多还原

【Abstract】 [Objective] To explore the simultaneous determination of hydrogen chloride and sulfate in the air of workplace by one sampling.[Methods] The porous glass plate absorber valve was used to sampling,the contents of hydrogen chloride and sulfate was determined by hydronium chromatography method at the best determination condition and suitable mobile phase.[Results] The quantitative lower limit and the relative standard deviation(RSD) of hydrogen chloride was 0.028 mg/m3 and 2.0%～3.8% respectively,and that of sulfate was 0.032 mg/m3 and 1.3%～4.2% respectively.The difference of determination results between this method and chemical method was not significant.[Conclusion] The method is simple,high sensitivity,precision,and pollution-free.更多还原
