“…Unfortunately, liquid nebulization sample introduction procedure for conventional ICP-MS is not compatible with SFODME because of its large sample consumption. Therefore, a lot of works on SFODME for separation and preconcentration of trace elements have been done by AAS, but only few researches were reported using ICP-MS (Chen, Cheng, He, Zhu, & Lu, 2013;Guo, He, Chen, & Hu, 2012).…”

Single solidified floating organic drop microextraction was used for the preconcentration and determination of Cd(II) and Pb(II). The procedure employed 1-(2-pyridylazo)-2-naphthol as a chelating agent, 1-undecanol as the extractant solvent, and methanol was as the dispersive solvent. Factors influencing the recovery of Cd(II) and Pb(II) such as the pH, volume of extractant, volume of ligand, volume of dispersant, and stirring time were optimized by Plackett Burman design. In order to complete the optimization, a central 2 3 +star orthogonal composite design was applied. The limits of detection for Cd(II) and Pb(II) were 0.15 and 0.52 µg L -1 . The validation of procedure was evaluated by the analysis of TMDA 70 Fortified Water and NCSDC-73349 Bush Branches certified reference materials. The determined values were in good agreement with the certified values. The single solidified floating organic drop microextraction method was employed for the determination of cadmium and lead in water, vegetables, and fruit.

“…Moreover, Guo et al. used a chelating agent for better extraction of heavy metal ions. It can be seen that there are many ways to influence the extraction, such as varying the type of solvent, its volume, addition of salt, stirring rate, temperature, etc.…”

“…Lower boiling solvent p-xylene was mixed with 1-dodecanol in a ratio such that the drop was still stable but the extract evaporated at lower temperature, which is advantageous for GC. Moreover, Guo et al [44] used a chelating agent for better extraction of heavy metal ions. It can be seen that there are many ways to influence the extraction, such as varying the type of solvent, its volume, addition of salt, stirring rate, temperature, etc.…”

Sample pretreatment techniques or preconcentration constitute a very important step before the analysis of environmental, clinical, pharmaceutical, and other complex samples. Thanks to extraction techniques it is possible to achieve higher method sensitivities and selectivities. Miniaturization microextraction methods make them more environmentally friendly and only small amounts of samples are required. In the past 30 years, a number of microextraction methods have been developed and used and are documented in thousands of articles. Many reviews have been written focusing on their use in specified professional fields or on the latest trends. Unfortunately, no uniform nomenclature has been introduced for these methods. Therefore, this review attempts to classify all the essential microextraction techniques and describes their advantages, disadvantages, and the latest innovations. The methods are divided into two main groups: single drop and sorbent‐based techniques according to the type of extraction phase.
