The ionic liquid of 1-hexyl-3-methylimidazolium hexafluorophosphate [HMIMPF6] was dispersed into the aqueous sample solution in fine droplets by ultrasound and was used as the extraction solvent; the phenylurea herbicides were concentrated into the ionic liquid phase. The extraction conditions, such as the volume of the extraction solvent, sonication and centrifugation time, ionic strength, and the emulsification-extraction temperature, were optimized.

The good recovery (68-100%) of target analytes was obtained from the water samples. The relative standard deviations (RSDs, n=6) ranged from 2.3-9.5%, and the limits of detection (LODs) for the herbicides were between 0.10 mu gL(-1) and 0.24 mu gL(-1).
