摘　　要：采用吹扫捕集、DB-624毛细管柱分离,气相色谱FID检测地表水和生活饮用水中的1,2-二氯乙烷,在0-530μg/L有较好的灵敏度和良好的线性关系,水样分析时,检测限为0.006 mg/L,加标回收率在91%-106%之间,平均相对标准偏差为3.3%。Using purge and trap, DB -624 capillarity column to separate, gas chromatography FID to examine 1,2 -dichloroethane in surface water and dringking water, this method has high sensitivity and good linear relationship between 0 μg/L and 530 μg/L. The detection limit is 0. 006 mg/L, the added RSD is between 91% and 106% , and the average relatively standard deviation is 3.3%.
