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, ...
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, ...
Relative liquidity and future volatility
(Elsevier, 2015)
The main contribution of this paper is to identify the strong predictive power of the relative, rather than the absolute, volume of orders over volatility. To this end, we propose a new measure, relative liquidity, which ...
Inorganic selenium speciation analysis in Allium and Brassica vegetables by ionic liquid assisted liquid-liquid microextraction with multivariate optimization
(Elsevier, 2017-03)
A highly sensitive vortex assisted liquid-liquid microextraction (VA-LLME) method was developed for inorganic Se [Se(IV) and Se(VI)] speciation analysis in Allium and Brassica vegetables. Trihexyl(tetradecyl)phosphonium ...
COMPARISON OF THE CASAGRANDE AND DROP-CONE PENETROMETER METHODS FOR MEASURING THE LIQUID LIMIT IN PUERTO RICAN SOILSCOMPARISON OF THE CASAGRANDE AND DROP-CONE PENETROMETER METHODS FOR MEASURING THE LIQUID LIMIT IN PUERTO RICAN SOILS

Assembly of magnetic nanoparticles at a liquid/liquid interface: Catalytic effect on ion transfer process
(Elsevier Science Sa, 2015-11-01)
The adsorption of cobalt (Co) and cobalt–boron (CoxB) magnetic nanoparticles (NPs) at a liquid/liquid interface is examined. The Co NPs have a remanent magnetization while the CoxB is completely demagnetized in the absence ...
Liquid-liquid microextraction without phase separation in a multicommuted flow system for diltiazem determination in pharmaceuticals
(ELSEVIER SCIENCE BV, 2011)
Liquid-liquid microextraction without phase segmentation was implemented in a multicommuted flow system for determination of the anti-hypertensive diltiazem. The procedure was based on ion pair formation between the drug ...
