摘　　要：实验采用顶空-气相色谱法对水样的一氯苯进行分析，优化顶空的前处理条件及气相色谱条件，方法最低检测浓度可达0．005mg／L，标准曲线的线性相关系数r^2=0．9999，线性范围为0．1～2mg／L，样品平均加标回收率在101．4％～103．4％之间，相对标准偏差在1．6％～6．94％之间。该方法操作操作简单，重现性好、检出限低，适合水中一氯苯的检测。The experimental adopts Headspace - Gas Chromatography method on analyzing 1-chlorobenzene in water sample, which optimizes pre-treatment and GC condition of Headspace - Gas Chromatography. The method could achieve the minimum detectable concentration to 0.005mg/L, the relevant linear correlation coefficient of standard curve to 0.9999, the linear range between 0.1 mg/L to 2mg/L, the average added recovery between 101.4% to 103.4%, and the relative standard deviation between 1.6% to 6.94%. The method fits the detection of 1-chlorobenzene in water with simple operation, good reproducibility, and low detectable concentration.
