摘　　要：利用气相色谱火焰光度检测法测定轻烃及其产品中的含硫化合物,考察了实验条件,并研究了适合于测定的各种标准曲线类型.结果表明,含2-丙硫醇、1-丙硫醇和甲硫醚的测定下限分别为0.56,0.21,0.37 mg/L.The sulfur compounds in light hydrocarbon and its products were determined by gas chromatography with a flame photometric detector. The experimental conditions were examined and some types of standard curves were studied in detail. The determination limits of 2-propyl mercapan, 1-propyl mercapan and methyl thioether are 0.56,0.21 and 0.37 mg/L, respectively. The proposed method was applied to the determination of sulfur compounds in light hydrocarbon and its products and the results obtained are satisfactory.
