Recent advances in coupling single-drop and dispersive liquid-liquid microextraction with UV-vis spectrophotometry and related detection techniques

Novel miniaturized extraction techniques such as single-drop microextraction (SDME) and dispersive liquid-liquid microextraction (DLLME) are currently receiving a great deal of interest from analytical chemists, as evidenced by the continually growing number of original papers and reviews devoted to these techniques. Yet despite the fact that numerous reviews devoted to SOME and DLLME have already been published, we would like to offer our point of view on the state-of-the-art approaches that enable the coupling of SOME and DLLME with UV-vis spectrophotometric and related detection techniques. Examples of the discussed techniques are given in the tables. (C) 2011 Elsevier B.V. All rights reserved.
