摘要
确立了水中莠去津、乙草胺残留量检测方法。样本采用固相萃取提取净化，用气相色谱法在同一根色谱柱上分离后分别进入氮磷检测器（ＮＰＤ） 、电子捕获检测器（ＥＣＤ）进行检测。莠去津、乙草胺平均回收率分别为８８－９％ ～９１－５ ％ 和９０－７％ ～９６－５％ ；相对标准偏差分别为９－７ ％ 和５－６％ ；线性相关系数分别为０－９８９ 和０－９９５ 。
A method was developed to determine atrazine and acetochlor in water.The procedure included solid-phase extraction, clean up and determination by GC using single capillary column and NPD and ECD detector.The average recoveries of atrazine and acetochlor were 88.9%～91 5% and 90.7%～96 5%,the coefficients of variation were 9.7% and 5.6%,the linear correlation were 0.9897 and 0.9958 ,respectively.
