摘要: Dispersive liquid-liquid microextraction (DLLME) has become a very popular environmentally benign sample-preparation technique, because it is fast, inexpensive, easy to operate with high enrichment factor and consumes low volume of organic solvent. DLLME modified solvent extraction method in which acceptor-to-donor phase ratio greatly reduced compared other methods. In this review, order encourage further development DLLME, its combination different analytical techniques such as gas chromatography (GC), high-performance liquid (HPLC), inductively coupled plasma-optical emission spectrometry (ICP-OES) electrothermal atomic absorption (ET AAS) will be discussed. Also, applications conjunction solid-phase (SPE), solidification floating drop (SFO) supercritical fluid (SFE) are summarized. This review focuses on the extra steps sample preparation for application matrixes food, biological fluids solid samples. Further, recent developments presented. does have some limitations, also discussed detail. Finally, an outlook future technique given.
