| Abstract: | 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. |
