摘　　要：利用以单壁碳纳米管为涂层的固相微萃取纤维,通过气相色谱联用方法,研究了不同试验条件对萃取效率的影响,并建立了水中百菌清、三唑酮、稻瘟灵和异菌脲4种杀菌剂的分析方法.结果表明,单壁碳纳米管固相微萃取纤维能在p H为1的条件下正常工作,对上述杀菌剂有很好的萃取能力.该方法灵敏度高,可满足环境水样的农残检测要求.Solid phase microextraction （SPME） fiber coated with single-walled carbon nanotubes （SWCNTs） was prepared. An an- alytical method based on SPME-GC-ECD method was established for the detection of chlorothalonil, triadimefon, isoprothiolane, iprodione in water and the effects of experimental conditions on extraction efficiency were investigated. The results showed the ex- traction capacity of SWCNTs fiber for those fungicides was excellent that could be used at pH as low as 1. High sensitivity of the method was able to meet the requirements of enviromental sample tests of fungicides residues.
