建立了顶空-毛细管柱-FID气相色谱检测地表水中氯丁二烯的方法。采用HP-INNOWAX色谱柱分离,优化了分流比及顶空条件,氯丁二烯在1~90μg/L的范围内获得了良好的线性关系(r=0.9994),检出限(S/D=10)为0.01μg/L,地表水实际样品的加标回收率为98.5%~104.3%,相对标准偏差为2.45%。该方法操作简便、快速、灵敏度高,准确度和精密度均能满足检测要求,适用于地表水中氯丁二烯的检测。
建立瞭頂空-毛細管柱-FID氣相色譜檢測地錶水中氯丁二烯的方法。採用HP-INNOWAX色譜柱分離,優化瞭分流比及頂空條件,氯丁二烯在1~90μg/L的範圍內穫得瞭良好的線性關繫(r=0.9994),檢齣限(S/D=10)為0.01μg/L,地錶水實際樣品的加標迴收率為98.5%~104.3%,相對標準偏差為2.45%。該方法操作簡便、快速、靈敏度高,準確度和精密度均能滿足檢測要求,適用于地錶水中氯丁二烯的檢測。

A method of headspace capillary GC for determination of chloroprene in surface water was establish.Chloroprene was separated by HP-INNOWAX capillary column.With optimal shunt ratio,chloroprene showed a good linear range from 1~90 μg/L(r=0.9994).The method detection limint(S/D=10) was 0.01 μg/L,recovery was in the range of 98.5 %~104.3 %,and RSD was 2.45 %.The established method is convenient,fast,sensitive and accurate,and can be used for determination of chloroprene in surface water.
