Abstract: | The establishment of new analytical methods which improve quality and sensitivity in the determination of environmental pollutants
in liquid and solid samples is demanded. The use of micellar systems have become an advantageous tool for the extraction of
pollutant compounds, due to their easy handling, biodegradability, and the one-step procedure, and they are compatible with
the hydroalcoholic mobile phases used in HPLC. The focus of this review is to present recently developed methods and the main
trends in the use of micellar media combined with solid-phase microextraction and solid-phase extraction in the chromatographic
analysis of organic compounds in different types of environmental matrix, including water, sediments, and biological samples.
Selected samples illustrate the benefits of these systems in the whole of analytical process. The advantages of micellar media
over conventional extractants are reduction of solvent usage, low cost, easy handling, and non-toxic procedure. |
