Determination of Hydrogen Sulfide in Fuel Oil by Headspace Gas Chromatography-Fluorescence Detection
At present,hydrogen sulfide(H2S)in fuel oil is primarily detected using rapid liquid-phase extraction and gas chromatography methods.To address the issues of complex sample pretreatment,significant human error,and potential instrument damage associated with these methods,the article employs headspace sampling gas chromatography with fluorescence detection for accurate measurement of H2S in fuel oil.The results indicate that the headspace sampling gas chromatography-fluorescence detection technique achieves a correlation coefficient above 0.99 for H2S measurement,with a quantitation limit and detection limit of 0.3 mg/kg and 0.1 mg/kg,respectively,and an RSD of less than 4.0%.In practical fuel oil testing,the measurement results for H2S content using this technique showed no significant difference compared to the British Petroleum Standard IP 570/15 Determination of Hydrogen Sulfide in Fuel Oils-Rapid Liquid Phase Extraction Method,with a relative error of less than 4.0%.This confirms the accuracy of the headspace sampling gas chromatography-fluorescence detection technique for determining H2S content in fuel oil.The establishment of this detection method provides a reference for the development of H2S detection methods in the fuel oil and petrochemical industries,simplifying the sample pretreatment process and improving detection efficiency.
