      Liquid-Liquid Microextraction Combined with High-Performance Liquid 
      Chromatography.

AB  - Shaker-assisted dispersive liquid-liquid microextraction (SA-DLLME) and 
      surfactant dispersive liquid-liquid microextraction (SDLLME) have been developed 
      to determine five diphenylether herbicides in water samples using 
      high-performance liquid chromatography with photodiode array detection 
      (HPLC-PDA). For SA-DLLME, an up-and-down shaker-assisted emulsification was used. 
      Extraction was complete in 3 min. Only 30 muL of decyl acetate was required, 
      without a dispersive solvent. The linear range was from 2 to 1000 mug L-1, the 
      coefficient of determination (r2) was better than 0.9992, and the limit of 
      detection (LOD) was from 0.62 to 1.74 mug L-1. The relative recovery (RR) ranged 
      from 90 to 102% for river water, 88 to 104% for lake water, and 93 to 102% for 
      irrigating water. In SDLLME, a microsyringe was used to withdraw and discharge a 
      mixture consisting of an extraction solvent and 1 mg L-1 Tween 60 as a surfactant 
      four times within 10 s to form an emulsified solution. The linear range for the 
      target compounds was from 2 to 1000 mug L-1. The LODs were between 0.72 and 1.38 
      mug L-1. The RR ranged from 95 to 108% for river water, 96 to 109% for lake water, 
      and 86 to 114% for irrigating water.
