| Abstract: | Objective The selection of SPE column to extract trace pesticides in the water. Methods Investigated the recovery of 6 kinds SPE column (including HLB,GDX403,GDX103,C18,C8,C6) to extract phorate, sulfotep, propoxur, carbofuran, cypermethrin, fenvalerate in the water. Results By using oasis HLB cartridge to extract 21 kinds of pesticides in water, the recoveries were over 60%for the most pesticides. Conclusion The method could be applied to the cases which extract and analyse the trace pesticides in large volume water. |
