Advanced Analytical Microextraction Techniques and There Applications: A Review

Kassa Belay


In recent years, substantial research has been devoted to the development of new liquid-liquid microextraction methods for sample preparation. These microextration methods were performed by several techniques such as: liquid-phase microextraction (LPME) or membraneassisted solvent extraction (MASE), hollow fiber liquid phase microextraction (HF-LPME), single drop-phase microextraction (SDME), liquid-liquid-liquid-microextraction (LLLME), dispersive liquid-liquid microextraction (DLLME), and ionic liquid dispersive liquid-liquid microextraction (IL-DLLM). For performance extraction, increasing the ultrasound field utilized techniques such as: ultrasound-asisted liquid phase microextraction (ULPME), ultrasound-asisted ionic liquid dispersive liquid-phase microextraction (UILDLPM), ultrasound-asisted dispersive liquid-liquid microextraction (UDLLME), and ultrasoundasisted headspace liquid-phase microextraction (UHS-LPME) for extraction from a complex matrix. Also, microwave field was used for solid sample preparation improvement. Other techniques such as solid phase extraction (SPE), solid phase microextraction (SPME,) and stir bar solvent extraction (SBSE) were frequently used in liquid sample preparation.

Keywords: liquid-liquid extraction, microwave assisted extraction, sample preparation, solid phase extraction, ultrasound assisted extraction.
