Abstract
Classical techniques of extraction and preconcentration of analytes such as Liquid-Liquid extraction (LLE) and Solid Phase Extraction (SPE) have sorne drawbacks such as high consumption of organic solvent and time consuming in many cases. To solve these limitations, new techniques and methodologies so called Microextraction Techniques, which use low organic solvent amounts, have been developed. In this work a review ofthese techniques and their application to the extraction and preconcentration of emerging contaminants in environmental liquid samples is presented.
