摘　　要：建立了气相色谱法测定工业废气中的氯化氰含量的方法。采用PE GC580型气相色谱仪,电子俘获检测器,Rt-PlotQ色谱柱,采用外标法定量。氯化氰浓度在0.1~10 mol/mol范围内与峰面积呈良好的线性关系,相关系数大于0.999,9次重复测定结果的相对标准偏差小于4%,样品加标回收率为95%~104%。结果表明该方法简单、快速,测试结果准确可靠,满足废气中氯化氰含量的测试。The melhod for determination of cyanide chloride in industrial waste gas by gas chromatography was established,electron capture detector,Rt-PlotQ column.The quantitative analysis of cyanogen chloride in industrial waste gas was carried out by external standard method.Under the determination conditions,the mass concentration of cyanogen chloride was linear with the chromatographic peak area in the range of 0.1-10 mg/L,the linear correlation coefficient was 0.999.The relative standard deviations of determination results were 4%(n=9),the recoveries of spiked sample were 95%-104%.The method is simple and fast,the result is accurate and reliable,which is suitable for the determination of cyanogen chloride content in industrial waste gas.
