| 摘 要： | 本文研究了利用毛细管柱分离、测定水样中的苯系物。该方法用二硫化碳萃取水样中的苯系物，细口径毛细管柱分离，ＦＩＤ测定。在分流比为１００∶１的条件下，方法最低检出浓度在００２５～００４７ｍｇ／Ｌ之间，低于填充柱法。该方法适用于地表水、地下水和废水中微量苯系物的测定。

| Abstract: | A GC method for separating and determining benzols in water samples has been developed The analytical procedures are as follows:extration by CS 2,separation with capillary column and detrmination by FID The detection limit is 0 025mg/L to 0 047mg/L and lower than POLT column The method can be used to determine benzols in various kinds of water and wastewater |
