Application of switchable hydrophobicity solvents for extraction of emerging contaminants in wastewater samples
(MDPI, 2020)
In the present work, the effectiveness of switchable hydrophobicity solvents (SHSs) as extraction solvent (N,N-Dimethylcyclohexylamine (DMCA), N,N-Diethylethanamine (TEA), and N,N-Benzyldimethylamine (DMBA)) for a variety ...
A procedure for determination of cobalt in water samples after dispersive liquid–liquid microextraction
(Elsevier, 2009)
In this work, a procedure for preconcentration of cobalt using dispersive liquid–liquid microextraction (DLLME) with the reagent Br-TAO as complexing reagent was developed. The procedure is based on a ternary system of ...
Narrowing the interface between sample preparation and electrochemistry: Trace-level determination of emerging pollutant in water samples after in situ microextraction and electroanalysis using a new cell configuration
(2018-06-10)
In this work, a new cell configuration that enables the in situ integration of sample preparation and electrochemical detection prior analysis at trace-level is described. To perform the microextraction, a green chemistry ...
Ionic liquid-based microextraction techniques for trace-element analysis
(Elsevier, 2014-09)
Ionic liquid-based liquid-liquid microextraction (IL-LLME) techniques are turning into remarkable tools to develop greener sample-preparation methods in analytical chemistry. The application of ILs in LLME is receiving ...
High-throughput determination of phenolic compounds in virgin olive oil using dispersive liquid-liquid microextraction-CZE microextraction-capillary zone electrophoresis
(Wiley Vch Verlag, 2013-06)
This article reports a simple methodology using dispersive liquid-liquid microextraction (DLLME) combined with CZE. It has been applied for the simultaneous determination of phenolic compounds such as caffeic, gallic, ...
Analysis of non-polar heterocyclic aromatic amines in beefburguers by using microwave-assisted extraction and dispersive liquid–ionic liquid microextraction
(Elsevier, 2013-12)
A new sample preparation procedure to determine six heterocyclic aromatic amines (3-Amino-1,4-dimethyl-5H-pirido[4,3-b]indole, 3-Amino-1-methyl-5H-pirido[4,3-b]indole, 2-amino-1-methyl-6-phenylimidazo-[4,5-b]pyridine, ...
Determination of estrogenic mycotoxins in environmental water samples by low-toxicity dispersive liquid-liquid microextraction and liquid chromatography-tandem mass spectrometry
(Elsevier B.V., 2015-04-24)
A novel, simple, rapid and eco-friendly method based on dispersive liquid-liquid microextraction using a bromosolvent was developed to determine six estrogenic mycotoxins (zearalenone, zearalanone, alpha-zearalanol, ...
Solvent-based de-emulsification dispersive liquid-liquid microextraction coupled with UPLC-MS/MS for the fast determination of ultratrace levels of nitrated and oxygenated polycyclic aromatic hydrocarbons in environmental samples
(Royal Society of Chemistry, 2018-02)
In this study, a new solvent-based de-emulsification dispersive liquid-liquid microextraction strategy followed by liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry has been developed ...
