摘　　要：1 ,4 -二恶烷经常会在河水、特别是地下水中被检测到 ,这主要是由于挥发性的卤代碳氢化合物造成的污染。利用自制的活性炭小柱与PS -2小柱串联 ,将待测的工业废水样品通过小柱 ,经淋洗、浓缩 ,用GC -MS定量分析。结果证明 ,此方法样品用量少 ,处理程序简单 ,方法回收率较高 。Dioxane has been frequently detected in river water,especially in ground water polluted by volatile halogenated hydrocarbons.Wastewater samples were passed through the Self-made activated carbon cartridge and PS-2 cartridge connected in a series.The desorbed and concentrated solution of 1,4-Dioxane was analyzed by GC/MS. The results showed that only small amount of samples were needed in this method.Simple sample pretreatment and high recovery were proved.
