DESULPHURIZATION STUDY OF PETROLEUM PRODUCTS THROUGH EXTRACTION WITH AQUEOUS IONIC LIQUIDS
(Sociedad Chilena de Química, 2010)
Development of a dispersive liquid-liquid microextraction technique for the analysis of aryloxyphenoxy-propionate herbicides in soy-based foods
(Elsevier Science, 2016-06)
In this work, an ionic liquid–dispersive liquid-liquid microextraction (IL-DLLME) method combined with liquid chromatography and diode-array detection (DAD) was used for the determination of four aryloxyphenoxy-propionate ...
Understanding the destructuration of starch in water–ionic liquid mixtures
(Royal Society of Chemistry, 2015-05)
The destructuration of native maize starch in mixtures of water and ionic liquids (ILs) containing acetate anions was studied in dynamic heating conditions, combining calorimetry, rheology, microscopy and chromatographic ...
Ionic Liquid Stationary Phases In Gas Chromatography: Fundamentals, Recent Advances, And Perspectives
(Soc Brasileira QuimicaSão Paulo, 2016)
Bioanalytical separation and preconcentration using ionic liquids
Ionic liquids (ILs) are non-molecular solvents, which display a number of unique properties such as negligible vapor pressure, thermal stability even at high temperatures, favorable viscosity and miscibility with water and ...
Sensitive determination of thallium species in drinking and natural water by ionic liquid-assisted ion-pairing liquid-liquid microextraction and inductively coupled plasma mass spectrometry
A fast and simple method involving separation and determination of thallium (Tl) species, based on novel ionic liquid-assisted ion pairing dispersive liquid-liquid microextraction (DLLME) method, was developed. Initially, ...
