Abstract: The pesticide residues in environment water could not be detected directly, because the content was much lower than the limit of detection (LOD) of analysis instrument. The bottle-neck was how to enrich the targets. In this paper, it was reviewed that the research progress of enrichment and purified technology of the pesticide residues in environment water in recent years. It was focused on the discussion of influence factors of liquid - liquid extraction (LLE), such as: the selection of extraction solvent, mode of vibration, mode of condense, phenomenon of emulsification and salt out, pH, purification of extractions; of solid phase extraction (SPE), such as: the selection and activation of absorbent material, breakthrough volume, sample flow rate, moisture removal, leaching of the SPE cartridge, elution of the targets, pH and NaCl, purification of the elution solvent. Some new type enrichment methods were briefly introduced, and their disadvantages were discussed. The directions for future research were forecasted on the enrichment and purified technologies of pesticide residues in environment water.
