摘要
文章研究水中环氧氯丙烷的气相色谱方法。采用二氯甲烷萃取,DB-5,30m80.32mm80.25μm弹性石英毛细色谱柱分离,电子捕获检测器(ECD)检测环氧氯丙烷,环氧氯丙烷的回收率在94.9%~113%之间。测定结果的相对标准偏差为0.7%,得到了良好的分离效果、较宽的线性关系和较高的灵敏度,方法简便、快捷,该法可满足地表水环境质量标准的要求。
Epiehlorohydrin in water was detected by gas chromatography method, separated with DB -5,30 m * 0. 32 mm * 0.25 μm column, detected by ECD detector. The recoveries of Epiehlorohydrin were 94.9% - 113% , the RSD of determination were 0. 7%. This method has high sensitivity, precision, and wide linearity. The method is simple, fast. The results could meet the requirement of GB3838 - 2002.
