摘　　要：实验采用吹扫捕集-气相色谱法对水样的一氯苯进行分析,优化吹扫捕集的前处理条件及气相色谱条件,方法最低检测浓度可达0.007mg/L,标准曲线的线性相关系数r2=0.9999,线性范围为0.1～2mg/L,样品平均加标回收率在96.5%～103%之间,相对标准偏差在4.58%～5.82%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 Purge and Trap-Gas Chromatography method on analyzing 1-chlorobenzene in water sample,which optimizes pre-treatment and GC condition of Purge and Trap-Gas Chromatography.The method could achieve the minimum detectable concentration to 0.007mg/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 96.5% to 103%,and the relative standard deviation between 4.58% to 5.82%.The method fits the detection of 1-chlorobenzene in water with simple operation,good reproducibility,and low detectable concentration.
