Pesticides are widely used today and are easily remained in grain, vegetables, water, etc, which will do great harm to human health.HPLC is a common chromatographic method which has been used to detect pesticides.However, these methods used exclusive and expensive fluorescence or MS detector.If UV detector is used, large volume Liquid-liquid extraction (LLE) and off-line solid phase extraction (off-line SPE) must be adopted for enrichment to reach lower limit of detection.However, LLE and off-line SPE have their distinct deficiencies, such as use of large quantities of organic solvents, poor reproducibility, and so on.
