Disolventes nanoestructurados para la microextracción de astaxantina y cantaxantina en productos de piscifactoría
(Universidad de Córdoba, 2011)
Tunable solvency mixtures of tetrahydrofuran: water for efficient and fast extraction/clean-up of trace contaminants
(Elsevier, 2019)
In this study, we investigated the potential of mixtures of tetrahydrofuran (THF) and water as tunable solvents for the microextraction of contaminants in solid and in liquid matrices. These two miscible solvents have very ...
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 ...
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, ...
Valorization of spent coffee grounds by supramolecular solvent extraction
(Elsevier, 2019)
In this study, we assess the potential of supramolecular solvents (SUPRAS) for valorization of spent coffee grounds (SCG). SUPRAS, made up of self-assembled amphiphilic aggregates dispersed in an aqueous or hydro-organic ...
