Abstract
Dispersive liquid-liquid micro extraction (DLLME) has become a very popular environmentally benign sample-preparation technique, due to its simplicity, rapidity of operation and low consumption of solvent and reagent. It has attracted much interest from scientist working in separation science and much improvement has been made since its introduction in 2006. It has been combined with different extraction techniques such as floating organic drop, solid-phase extraction, and supercritical fluid extraction. This seminar has focused on the review on development of dispersive liquid micro extraction (DLLME) and its application in different samples, such as water, soil, food and biological material with different analytical techniques.

Highlights
1.1 Back ground of study In spite of substantial technological advances in analytical field, most instruments cannot directly handle complex sample matrixes yet
The results indicated that dispersive liquid–liquid micro extraction (DLLME) is a sensitive, rapid and reproducible technique that can be used for preconcentration CBs from water samples
The designed method was successfully applied for the preconcentration and determination of the studied synthetic antioxidants in different fruit juice samples, and satisfactory results were obtained [105].For the determination of macrocyclic lactones in milk, DLLME followed by liquid chromatography with diode array detection and atmospheric pressure chemical ionization ion-trap tandem mass spectrometry was developed [106]
Summary
1.1 Back ground of study In spite of substantial technological advances in analytical field, most instruments cannot directly handle complex sample matrixes yet. A simultaneous ionic liquid-based microwave-assisted dispersive liquidliquid micro extraction (IL-based MADLLME) method was developed for the determination of plasticizers in water using HPLC with ultraviolet detection.
