Review on the application of liquid phase microextraction in pesticide residue analysis

Liquid phase microextraction(LPME) is one of novel sample pretreatment techniques which has many advantages such as quick,simple,economic,highly selective and accurate,less-solvent consuming and environmental friendly.It can be matched easily with most of analytical instruments.It includes several types such as single drop microextraction(SDME),hollow fiber liquid phase microextraction(HF-LPME),dispersive liquid-liquid microextraction(DLLME),solidified floating organic drop microextraction(SFODME),continuous-flow microextraction(CFME) and directly-suspended droplet microextraction (DSDME) etc.It is a very potential sample pretreatment technique for theoretic and application studies.In this review,the historical development and overview of these miniaturized liquid phase extraction methodologies were discussed and a comprehensive collection of application of these methods for preconcentration and determination of pesticide residue in various matrices were summarized.
