“…Surfactants were especially convenient, because of their capacity to dissolve and extract different types of organic contaminants present in the environmental solid samples [271][272][273]. For example, Merino et al [272] tested the potential of anionic surfactants for the acid induced cloud point extraction (ACPE) and pre-concentration of PAHs from environmental solid samples by investigating their propensity to undergo clouding and liquid-liquid separation at elevated temperatures.…”

“…The use of microwave energy provided a great extractant capacity for a simple and rapid analysis of a variety of pollutants. For instance, microwave assisted micellar extraction (MAME) was applied to the extraction of polychlorinated dibenzofurans (PCDFs) [271] and polychlorinated biphenyls (PCBs) [273] from marine sediments, using two non-ionic surfactants (oligoethylene glycol monoalkyl ether and polyoxyethylene-10-lauryl ether) as extractants.…”

The analytical performances and applications of various luminescence spectrometric methods to the study and determination of pollutants present at low levels in the environment are reviewed for the last two decades (1990 – 2010). The first part concerns luminescence stationary systems, including fluorescence, photochemically-induced fluorescence, phosphorescence and related luminescence methods. In the second part, the combination of these luminescence methods with flow techniques such as high performance liquid chromatography (HPLC), capillary electrophoresis (CE) and flow injection analysis (FIA) for the detection and determination of environmental pollutants is investigated. A part of the review is also devoted to the usefulness of organized supramolecular systems, such as micellar media, cyclodextrins and calixarenes, for improving the efficiency of luminescence methods.

“…Among the different types of surfactants, the non-ionic ones have been widely used to extract organic substances from diverse types of samples [ 74 , 75 , 76 , 77 , 78 , 79 , 80 ] which demonstrates their high potential as extractants. Moreover, they are compatible with aqueous–organic mobile phase in chromatographic analysis, which facilitates these applications.…”

Methodologies for the Extraction of Phenolic Compounds from Environmental Samples: New Approaches

et al. 2009

Phenolic derivatives are among the most important contaminants present in the environment. These compounds are used in several industrial processes to manufacture chemicals such as pesticides, explosives, drugs and dyes. They also are used in the bleaching process of paper manufacturing. Apart from these sources, phenolic compounds have substantial applications in agriculture as herbicides, insecticides and fungicides. However, phenolic compounds are not only generated by human activity, but they are also formed naturally, e.g., during the decomposition of leaves or wood. As a result of these applications, they are found in soils and sediments and this often leads to wastewater and ground water contamination. Owing to their high toxicity and persistence in the environment, both, the US Environmental Protection Agency (EPA) and the European Union have included some of them in their lists of priority pollutants. Current standard methods of phenolic compounds analysis in water samples are based on liquid–liquid extraction (LLE) while Soxhlet extraction is the most used technique for isolating phenols from solid matrices. However, these techniques require extensive cleanup procedures that are time-intensive and involve expensive and hazardous organic solvents, which are undesirable for health and disposal reasons. In the last years, the use of news methodologies such as solid-phase extraction (SPE) and solid-phase microextraction (SPME) have increased for the extraction of phenolic compounds from liquid samples. In the case of solid samples, microwave assisted extraction (MAE) is demonstrated to be an efficient technique for the extraction of these compounds. In this work we review the developed methods in the extraction and determination of phenolic derivatives in different types of environmental matrices such as water, sediments and soils. Moreover, we present the new approach in the use of micellar media coupled with SPME process for the extraction of phenolic compounds. The advantages of micellar media over conventional extractants are reduction of organic solvent, low cost, easy handling and shorter time procedures.

“…This combination, called microwave-assisted micellar extraction (MAME) has been applied to the extraction of different compounds from solid matrices (Padrón- Sanz et al, 2002;Eiguren Fernández et al, 2001;Mahugo-Santana et al, 2004;Padrón Sanz et al, 2005). Among the advantages of the MAME are reduced volumes of extractant, low cost and reduced toxicity in comparison to organic solvents.…”
