“…The developed UFPSE-HPLC-UV method was compared to other methods in the published literature [10,11,[43][44][45][46][47]. As revealed in Table 5 below, our developed method demonstrates an analytical performance either better or within the range of the published results except for the methods that involve coupling highly sophisticated and much more expensive analytical instruments like mass spectrometers and tandem mass spectrometers.…”

Here, we deployed sol‐gel universal sorbent‐coated fabric phase sorptive extraction membranes in tandem with high‐performance liquid chromatography equipped with an ultraviolet detector (HPLC‐UV) for the analysis of 10 endocrine‐disrupting chemicals (EDCs). Due to the varying polarities of the studied compounds indicated by their octanol/water partition coefficient ‘log Kow’ (1.47–5.07), the extraction membrane was designed with different functionalities that are capable of simultaneous interaction with compounds of diverse natures including polar, non‐polar, and ionic species via sol‐gel sorbent coating technology. An isocratic mode of HPLC‐UV at 55:45% acetonitrile:water (v/v) on a reverse phase C18 Zorbax column (5 μm, 150 mm, 4.6 mm) was used for the separation and quantitation. Calibration curves were found linear between 25 and 2000 ppb for all compounds except cortisone in the range of 25–1000 ppb which provided an R2 value above 0.9940 in all cases. The intra‐day reproducibility and inter‐day reproducibility were found in the range of 1.2–12.8 and 0.2–14.1 (expressed as percent relative standard deviation), respectively. The validated method was finally deployed for the analysis of environmental water and milk samples with estradiol showing the highest concentrations among the studied compounds.

“…The driving forces exhibited during extraction were electrostatic, hydrophobic and π-cation interactions. New improvements in the research work using DES have been reported by Zhao et al [57] in the extraction of phenolic endocrine disrupting chemicals in envi-ronmental water. Acceleration of DES was encouraged by the presence of magnetic Fe 3 O 4 impregnated with porous activated carbon.…”

CO2-Effervescence in Liquid Phase Microextraction for the Determination of Micropollutants in Environmental Water: a Review

et al. 2021

Liquid phase microextraction is a state-of-the-art micro-analytical work with numerous advantages documented in the scientific literature. One of the most intriguing subclasses is the CO 2 -effervescence assisted dispersive liquid−liquid microextraction method. Working theory was based on an acid-based reaction involving a proton donor and a carbon dioxide source. The paper outlines the considerations regarding the microextraction performance that can change in terms of physical, chemical properties, and its application for environmental sample analysis. A wide range of the developed and applied novel methods clearly indicates that CO 2 -effervescence is still in demand among researchers looking for new achievements in green analytical chemistry. This review focuses on the method application for the extraction and preconcentration of different classes of micropollutants (organic or inorganic) in environmental waters. New breakthroughs in the microextraction process show enhanced performance of the system in terms of sensitivity, accuracy, precision and the attempt to reduce extraction steps during separation or retrieval processes for low concentrations of analytes. Future direction refers to the improvement of green parameters in the microextraction, use of extracting agents as co-dispersers (solid or liquid), removal of elution dependency in solvents by the use of super-paramagnetic properties, etc. The success stories of the method development are widely documented in the literature. This microextraction technique will continue to serve as a reliable tool for the determination of micropollutants in environmental samples.

“…In contrast, Arpa et al used an effervescent tablet to assist the mixing between the DES and the sample [ 81 ]. As it occurs with other solvents, magnetic nanoparticles [ 82 ] and the solidification technique [ 83 ] have been proposed for the separation of the DES after the extraction. Very recently, Shishov et al have proposed an interesting approach based on the use of DES in EA-DLLME [ 84 ].…”

Effervescence-Assisted Microextraction—One Decade of Developments

2020

View full text Add to dashboard Cite

Dispersive microextraction techniques are key in the analytical sample treatment context as they combine a favored thermodynamics and kinetics isolation of the target analytes from the sample matrix. The dispersion of the extractant in the form of tiny particles or drops, depending on the technique, into the sample enlarges the contact surface area between phases, thus enhancing the mass transference. This dispersion can be achieved by applying external energy sources, the use of chemicals, or the combination of both strategies. Effervescence-assisted microextraction emerged in 2011 as a new alternative in this context. The technique uses in situ-generated carbon dioxide as the disperser, and it has been successfully applied in the solid-phase and liquid-phase microextraction fields. This minireview explains the main fundamentals of the technique, its potential and the main developments reported.
