摘要
目的建立废气中H_2S检测的气相色谱法。方法用100 ml玻璃注射器采集H_2S气体,经GDX-104色谱柱分离后,应用火焰光度气相色谱法进行检测。结果该方法的线性检测范围为0.0005～0.85 mg/m^3;线性方程为y=33.532 89+ 1.92181 x(r=0.999 86),RSD为2.54%～3.89%,最低检出限为0.000 5 mg/m^3。结论该方法快捷,灵敏度高,结果准确,稳定性好,适合废气中H_2S的测定。
Objective To establish a gas chromatography method for the determination of hydrogen sulfide in waste gas. Methods Hydrogen sulfide was collected with 100 ml glass injector, then the sample was separated with the column of GDX-104, and it was detected by gas chromatography with the flame-photometric detector. Results The linear range was 0.000 5-0.85 mg/m^3, the linear equation was y=33.532 89＋ 1.921 81x （r=0.999 86）, RSD was 2.54%-3.89%, the lowest detected concentration was 0.000 5 mg/m^3. Conclusion This method is rapid, sensitive, accurate, stable and applicable to the determination of hydrogen sulfide in waste gas.
