Tetrahydrofuran–water extraction, in-line clean-up and selective liquid chromatography/tandem mass spectrometry for the quantitation of perfluorinated compounds in food at the low picogram per gram level
(Elsevier, 2010)
A new solvent extraction system was developed for extraction of PFCs from food. The extraction is carried
out with 75:25 (v/v) tetrahydrofuran:water, a solvent mixture that provides an appropriate balance of
hydrogen ...
Supramolecular solvent-based microextraction of ochratoxin A in raw wheat prior to liquid chromatography-fluorescence determination
(Elsevier, 2010)
A supramolecular solvent made up of reverse micelles of decanoic acid, dispersed in a continuous phase
of THF:water, was proposed for the simple, fast and efficient microextraction of OTA in wheat prior
to liquid ...
Coacervative extraction of Ochratoxin A in wines prior to liquid chromatography/fluorescence determination
(Elsevier, 2008)
Coacervates made up of reverse micelles of decanoic acid were assessed as a new strategy
for the simplification of wine sample treatment in the determination of Ochratoxin A (OTA).
Simultaneous extraction/concentration ...
Supramolecular biosolvents made up of self-assembled rhamnolipids: synthesis and characterization
(Royal Society of Chemistry, 2020)
Simple coacervation of surfactants constitutes a powerful bottom-up strategy for the production of tailored supramolecular solvents (SUPRASs), which feature outstanding properties in extraction processes. In this study, ...
Double-headed amphiphile-based sponge droplets: synthesis, characterization and potential for the extraction of compounds over a wide polarity range
(Elsevier, 2022)
Supramolecular solvents (SUPRASs) are gaining momentum in the multi-residue analysis of liquid samples thanks to the delimited hydrophilic and hydrophobic microenvironments in their nanostructures. In this work, SUPRASs ...
Determination of bisphenols A and F and their diglycidyl ethers in wastewater and river water by coacervative extraction and liquid chromatography–fluorimetry
(Elsevier, 2007)
A simple, rapid and sensitive analytical method was developed for the simultaneous determination of bisphenol A (BPA), bisphenol F (BPF) and their corresponding diglycidyl ethers (BADGE and BFDGE) in wastewater and river ...
Patente: Procedimiento para la extracción de licopeno utilizando fases líquidas nanoestructuradas
(Oficina de Transferencia de Resultados de la Investigación, 2023)
Potential of supramolecular solvents for the extraction of contaminants in liquid foods
(Elsevier, 2009)
Supramolecular solvents, which are water immiscible liquids consisting of supramolecular aggregates in the nano- and micro-scale regimes dispersed in a continuous phase, were assessed for the extraction of trace contaminants ...
Hemimicelles of Alkyl Carboxylates Chemisorbed onto Magnetic Nanoparticles: Study and Application to the Extraction of Carcinogenic Polycyclic Aromatic Hydrocarbons in Environmental Water Samples
(ACS, 2009)
In this work, magnetic nanoparticles (MNPs) coated with hemimicelles of alkyl (C10-C18) carboxylates, which have traditionally been used to prepare ferrofluids for technological applications, were used for the first time ...
Environment-Responsive Alkanol-Based Supramolecular Solvents: Characterization and Potential as Restricted Access Property and Mixed-Mode Extractants
(ACS, 2012)
Self-assembly, the process by which supramolecular solvents (SUPRAS) with an ordered structure are produced, provides unique opportunities to obtain tailored solvents with advanced functional features. In this work, ...
