摘要

  • 摘要: 本文采用液上气相色谱法测定水中硝基苯,5μl进样量的最低检出浓度为0.1mg/l;1ml进样量的最低检出浓度为1μg/l;在0.94—5.2mg/l浓度范围内,六次测定的相对标准偏差小于8.5%。应用本法可测定地面水及工业废水中的硝基苯。测定成份复杂工业废水中的硝基苯,与其它方法相比,本法较为简单。
    Abstract: A headspace gas chromatographic method for determinating nitrobenzene in water has been developed. For a sample of 5μl injected, the detection limit of the method was 0.5mg/l, with a relative standard deviation of less than 8.3%. The detection limit was found to be 1μg/1 for a sample of 1ml injected.The headspace-GC method is rather rapid and convenient especially for nitrobenzene-containing wastewater of complicated composition.
