| 摘 要： | 本文使用 GDX- 10 2大孔树脂对水中微量烷基苯类、硝基苯类、卤代苯类进行了同时富集 ,富集后的水样用两根极性不同的毛细管柱进行气相色谱双柱定性 ,外标法定量。本方法对十四种取代苯的加标回收率为 92 %～ 98% ,相对标准偏差在 5 %以下 ,最低检测限达 3.2 5× 10 -9g。采用的双毛细管柱定性方法操作简便 ,结果可靠

| Abstract: | Substituted benzenes in water were enriched with GDX-102 resins.The enrichment compounds were identified and quantified by double capil lary gas chromatography.The mean recovery of fourteen substituted benzenes is 92 %～98%，and the relation deviation is below 5%.The detection limited is 3.25×1 0-9g.It was found that the met-hods of double capillary GC were simple a nd efficient. |
