Sample pretreatment is a key part in the process of sample analysis.Some additional fields such as microwave，light，pressure and ultrasound，which are able to speed up mass transfer of solute or accelerate sample separation process，have been widely adopted in sample pretreatment.Electric field assisted sample treatment techniques have turn out to be a research hotspot in sample pretreatment due to its excellent extraction efficiency and selectivity in micro trace analysis.Moreover，these techniques have been successfully applied in food analysis，environment analysis and bio analysis.The progress of electrical field assisted extractions，including the electrical field assisted membrane extraction，solid phase micro extraction，liquid phase micro extraction is introduced in this review.Furthermore，the development trend of electric field assisted sample preparation techniques is prospected.
