“…This might happen because of the insufficient stirring of the solvent during the extraction. Other researchers [28,29] reported this phenomenon as Table 6 Precision data of the MAE procedure at a level of 100 ng of the target compounds well. The recovery of Irgarol 1051 was not affected by the increase of water volume.…”

“…In this technique the microwave energy produced by a high temperature microwave oven is especially useful for the analysis of soil and sediments samples [5][6][7]. If MAE is compared with other conventional methodologies, such as liquid-liquid or Soxhlet extraction, less energy, smaller volume of extractant and shorter time are required for analysis -moreover, the results are comparable with those obtained using these methodologies [8][9][10].…”

“…Therefore it would be necessary to optimise factors that control those relationships to obtain satisfactory recoveries [5,19]. In this work different parameters have been studied: solution pH, surfactant concentration, extracting power, and length of washing steps.…”

SummaryAnalysis of marine sediments is particulary important because they are considered pollution indicators, since they present a view of the spatial distribution of pollutants. The use of microwave energy enables a simple and rapid analysis of different kinds of compounds present in these media.This work shows the results obtained during the optimization process for the application of microwave-assisted extraction methodology (MAE) to the determination of polychlorinated dibenzofurans (PCDFs), present in different marine sediment samples, as well as in mixtures with polychlorinated biphenyls (PCBs), using lwo non-ionic surfactants (oligoethylene glycol monoalkyl ether and polyoxyethylene 10 lauryl ether) as extractants. After extraction, the organochlorinated compounds are determined by HPLC using fluorescence detection. Recovery rates are compared with those obtained when Soxhlet extraction is used for the same purpose.

“…Liquid-liquid extraction (LLE), SPE [25], microwave-assisted solvent extraction (MASE) [26], supercritical-fluid extraction (SFE) [27], and in-tube SPME [28] have been mostly used for the sample extraction of various plasticizers from different matrices.…”

Two approaches based on solidification of floating drop microextraction (SFDME) and homogenous liquid-liquid microextraction (HLLE) were compared for the extraction and preconcentration of di-(2-ethylhexyl) phthalate (DEHP) and di-(2-ethylhexyl) adipate (DEHA) from the mineral water samples. In SFDME, a floated drop of the mixture of acetophenone/1-undecanol (1:8) was exposed on the surface of the aqueous solution and extraction was permitted to occur. In HLLE, a homogenous ternary solvent system was used by water/methanol/chloroform and the phase separation phenomenon occurred by salt addition. Under the optimal conditions, the LODs for the two target plasticizers (DEHA and DEHP), obtained by SFDME-GC-FID and HLLE-GC-FID, were ranged from 0.03 to 0.01 microg/L and 0.02 to 0.01 microg/L, respectively. HLLE provided higher preconcentration factors (472.5- and 551.2-fold) within the shorter extraction time as well as better RSDs (4.5-6.9%). While, in SFDME, high preconcentration factors in the range of 162-198 and good RSDs in the range of 5.2-9.6% were obtained. Both methods were applied for the analysis of two plasticizers in different water samples and two target plasticizers were found in the bottled mineral water after the expiring time and the boiling water was exposed to a polyethylene vial.
