Under the coexistence of SO2and H2S, the concentration of hydrogen sulfide exhausted from stationary pollution source was measured by Portable-Gas-Chromatogram ( PGC ) method. The Portable-Gas-Chromatogram ( PGC ) method is simple and rapid, and the measured results can completely meet the requirement of H2S among complex components.%在SO2与H2S共存下,利用便携式气相色谱法测定了固定污染源排气中硫化氢含量.方法简便快速,准确度和精密度较高,受干扰物质二氧化硫的影响小,测定结果完全满足复杂成分烟气中硫化氢的测定要求.
