Determination of six veterinary pharmaceuticals in egg by liquid chromatography: Chemometric optimization of a novel air assisted-dispersive liquid-liquid microextraction by solid floating organic drop
(Elsevier, 2019-02)
Two extraction strategies for albendazole, chloramphenicol, trimethoprim, enrofloxacin, oxitetracycline and nicarbazin in egg were optimized for its quantitation by liquid chromatography. First, two designs were built to ...
Ion transfer across liquid|liquid interface under forced hydrodynamic conditions. I: Digital simulations
(Elsevier Science Sa, 2012-02)
In this paper, we present the general equations for a model that describes ion transfer reactions across the oil|water interface assisted by a ligand, under forced hydrodynamic conditions. Our analysis is mainly focused ...
Complexity and self-organized criticality in liquid foams. A short review
(Elsevier Science, 2020-11)
This short review deals with the work done on liquid foams within the framework of the physics of complexity. It aims to stimulate new theoretical and experimental work on foam dynamics as complex dynamical systems. In ...
Determining heterocyclic aromatic amines in aqueous samples: A novel dispersive liquid-liquid micro-extraction method based on solidification of floating organic drop and ultrasound assisted back extraction followed by UPLC-MS/MS
(Elsevier Science, 2017-11)
A novel dispersive liquid-liquid microextraction based on solidification of floating organic droplet combined with ultrasound assisted back extraction for the determination of four heterocyclic aromatic amines in natural ...
A natural deep eutectic solvent as a novel dispersive solvent in dispersive liquid-liquid microextraction based on solidification of floating organic droplet for the determination of pesticide residues
(Springer Heidelberg, 2021-08)
Current trends in analytical chemistry encourage the use of innocuous solvents to develop modern methods aligned with green chemistry. In this sense, natural deep eutectic solvents (NADESs) have emerged as a novel generation ...
Development of preconcentration strategies for the simultaneous ultratrace determination of As, Cd and Pb in foods by ICP-OES: knotted-reactor vs. dispersive liquid–liquid microextraction
(Royal Society of Chemistry, 2020-03)
Determination of As, Cd and Pb in food samples by means of inductively coupled plasma optical emission spectrometry (ICP-OES) is challenging due to detection limits being close to the maximum levels established by current ...
Capabilities of several phosphonium ionic liquids for arsenic species determination in water by liquid-liquid microextraction and electrothermal atomic absorption spectrometry
(Royal Society of Chemistry, 2015)
The capabilities of several phosphonium-ionic liquids (PILs) to form ion-pairs with a complex obtained by reaction of arsenate species with molybdate were evaluated. Phosphonium-ILs containing the tetradecyl(trihexyl)phosphonium ...
Interaction of chitosan and self-assembled distearoylphosphatidic acid molecules at liquid/liquid and air/water interfaces. Effect of temperature
(John Wiley & Sons Ltd, 2016-11)
The effect of the polyelectrolyte, chitosan (CHI), on distearoylphosphatidic acid (DSPA) films was analyzed by cyclic voltammetry, surface pressure-area isotherm, and Brewster angle microscopy. Distearoylphosphatidic acid ...
Study of enantioseparation of β-blockers using amylose tris(3-chloro-5-methylphenylcarbamate) as chiral stationary phase under polar-organic, reversed-phase and hydrophilic interaction liquid chromatography conditions
(Elsevier, 2020-12)
In this study, we describe the experimental variables influencing enantioseparation of twelve β-blockers when analyzed under polar-organic, reversed-phase and hydrophilic interaction liquid chromatography conditions on a ...
Dispersive liquid–liquid microextraction and gas chromatography accurate mass spectrometry for extraction and non-targeted profiling of volatile and semi-volatile compounds in grape marc distillates
(Elsevier Science, 2018-04)
The suitability of dispersive liquid–liquid microextraction (DLLME) and gas chromatography accurate mass spectrometry (GC–MS), based on a time-of-flight (TOF) MS analyzer and using electron ionization (EI), for the ...
